This is what retarded alt girls type when they are "laughing", 100% of the time it is annoying and ruin the joke. It isn't always "IHUDF-" and it could be anything from YEGFTR- to HAGDH-, the choices are unlimited. Please don't use this phrase ever!
Elizabeth: Girl Johnny just tried to ask me out today and I slapped him so fast lmfao.
Annoying Retard: IHUDF-

Elizabeth: Yeah I'm finna slap you too.
