When Melvin appeared in the alleyway, he yelled his infamous catchphrase "Sploopity Sploosh!"
During my presentation in class today, some Tard yelled out "Sploopity Sploosh!"
Synonymous to shwing coined by Wayne's World, sploosh is an onomatopoeia representing sexual release (male or female), and is therefore a symbol of arousal and attraction to another person.
Can also be coupled with a hand being extending from one's pelvic region, to physically represent said release.
Chick 1: Oh wow did you just see that guy's 6 pack?? He's so hot. Sploosh!
Chick 2: Oh yea for sure! Sploosh.
