Get the dumbfuckmug. 
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.
