Get the Happy sack mug.
much like it's 'happy slapping' brother. similar method but with a rather different act of shame. instead of brandishing the victim with a slap across the face, in this instance one aims to ejaculate on the victims facial area.
'dude, i happy spaffed this woman on the train - she totally didn't see it cumming. LITERALLY > muhahaha!'

'we did some grade A happy spaffing today at the bus stop'

*NB - This is a totally indecent act and should never be attemped by anyone ever. in the unfortunate circumstance that it happens by accident... then feel free to circulate the vids wont you.
