Why did my Chinese teacher describe Donald Trump as 口吐莲花? In my regular Chinese class yesterday, I was discussing Donald Trump with my teacher, and she described him as 口吐莲花 (kǒutǔliánhuā).  As always I didn't fully understand the particulars of the conversation, but I believe she was referring to his eye-catching, provocative speech and behavior (and contrasting it with Biden's lack of theatrics).  I'm interested in what about Donald Trump in particular makes him 口吐莲花.
Question: Why did my Chinese teacher describe Donald Trump as 口吐莲花?
It's hard to look up this term, e.g., YouDao gives &quot;vomit a lotus&quot; and Google Translate gives &quot;spit lotus&quot; which don't capture the non-literal aspects of this term.
「莲花出淤泥而不染」，象征纯洁 (lotus flower came from mud but not stained by it. Symbolizing purity.)

Your teacher described him as 口吐莲花 in an ironic way,  mocking his foul mouth

Idiom 舌灿莲花: 譬喻说话的文采和美妙 (&quot;the tongue sparks lotus flower&quot; refers to having the literary talent to speak beautifully.)

Again, ironically, your teacher was mocking his lack of literary talent and his incoherent speeches
