What means 狂擺 in Cantonese? I don't understand these two characters in Miss Hong Kong 2020 contestant Rosanna Tse's IG post. At 18 she's youngest.  She's thanking Miss Friendship, Maisie Kwong, who's 24.
Here's my translation of line 4. I presume 颠咗 means 傻了 in Cantonese.
Remember this silly girl was in front you posing sillyly 狂擺.

上次影咗唔記得po添
...諗嘢諗嘢諗嘢諗嘢...
多謝Maisie揸機
[4.] 望住個傻妹係你面前顛咗咁狂擺pose
你影相好靚❣
記得呢日係第一次通宵，我地都仲係精神寶寶
多謝你成日陪我傾計❤❤❤
要繼續咁靚女喔
