when she wants to get roasted but doesn't know you are too sarcastically literal:

LOL

*roaster her like how i roast chicken*

she doesnt look a day over 55

true

she looks like if you fused a karen on facebook with a 14 year old white girl on tik tok

ok…

wowowowowowowowowowowowowoowoowowoooowoowowowooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo

if you roast her, you are weird because it's weird to talk to trash

That was ok but you could phrase that differently.
Like:
I would roast you, but my mom says I’m not allowed to burn trash.

but thats a self roast bc you never burned urself
