No it doesn't just examine the context.
Your pay is biweekly (who would actually think you'd get paid twice a week)?
This is a friendly reminder to read our rules.
Remember, /r/Showerthoughts is for showerthoughts, not "thoughts had in the shower!"
(For an explanation of what a "showerthought" is, please read this page.)

Yess. Bring back fathoms and fortnights. I’m on board. >

Fathoms? >

That's deep, man. >

About a man deep in fact >

I’m only bi twice every two weeks. Can’t get much clearer than that >

So once a week? >

No, it's like when you double walk to run. >

This man half double runs >

Most dictionaries I’ve seen recognise both usages as valid.
When I hear it my first thought is twice a week. Similar to biannual. If you mean every two weeks, use “fortnightly” instead. >

prior to this post, you've looking up biweekly in multiple dictionaries? >

Yes, believe it or not, this shower thought was not the first time in human history that someone thought about this. >

Biweekly meeting = every other week,
Biweekly donuts = twice a week >

Got it! Context matters. Things you want are twice a week. Things you don’t want are less often >

I know I also never know the what semi-annual means does it mean twice a year or every two years? English is very confusing >

Semi-annual is twice a year.
Bi-annual could go either way. >

I feel like people sometimes try to use semi-annual interchangeably with bi-annual, but I always interpreted them as having specific meaning. Context is important, but technically they mean two very different things. 
The real question is:  should we start using semi-weekly to denote twice a week? 
~or~ 
Do people just need remedial English classes? 
The two have very different, often conflated meanings, but they are well-defined enough that people shouldn’t have to ask this. 
I feel like this makes the most sense to me because bi-annual pretty much means ‘two-yearly’, whereas semi means half, so ‘half-yearly’. 
I thought pretty much everyone interpreted it this way because practically everyone knows the what ‘bi’ and ‘semi’ mean. Guess not. >

Of course you’re hidden premise is that words have fixed meanings dictated from on high and aren’t just whatever everyone agrees they mean. >

The main problem with English is that people just ignore the rules and then say these are the new rules. 
Bi means two, semi means half. A bicycle has two wheels, it doesn't have half a wheel. A semi-circle is half of a circle. >

You Bi-posted, not Semi-posted. >

When is "bi" ever twice in one  and not "semi"? Bi prefix always seems to imply "two", a bicycle has two wheels, bisexuals are attracted to two genders, you get paid biweekly, every two weeks. Semi is always half, like a semicircle is half a circle. My semiannual haircut is coming up, etc. >

Go ahead and bisect that logic >

But are we cutting it in two or cutting it in half? >

Many people get paid bi-weekly. Every two weeks. Biennial events happen every other year. Semi is twice per whatever unit. >

You mean bi weekly isn’t the number of bi people you meet in an average week? >

I go grocery shopping once a week…you could say i buy weekly >

Bi weekly means every 2 weeks, twice a week or semi weekly means twice a week. >

I need more evidence that twice a week means twice a week. >

I dont know how someone could ever think it would mean every 14 days. BIweekly. Twice a week.
