LMAOAOWKWNS

A phrase that is legally only allowed to be used by mochi ♡#2814 on discord. It is seen as very disrespectful if you do not have permission from her. It is usually used to express great laughter or surprise. Most likely both.

“Oh my god that was so funny I’m gonna put this shit on urban dictionary”
“ LMAOAOWKWNS”
