Dumbfuck

a stupid person tht is just a plain fuck up and has no life what so ever. most dumbfucks are reading this now because someone called them this and they dont know what the hell it means. well now u know dumbfuck.

another meaning is to not know who to fuck or have intercourse because of that one day you skipped sex ed class because you were grossed out so now your holding ur penis in your hand wondering where.to put it in the women. since your a dumbfuck you go for the armpit.

1- that guy over there is just a plain dumbfuck.

2- girl 1: how was u and your date last night wink wink

girl2: terrible afterwarda we went to have sex.and he stuck his penis in my armpit trying to dumbfuck.

dumbfungo

A person who writes or says things a level below stupid.

Stop being such a dumbfungo. You write like a dumbfungo. Your comments made as much sense as if it was written by a dumbfungo.

Anyone named Matt Ryan who spells alike, a like. A poser. A guy who jerks other guys and takes loads of semen in the face.
