A masturbation party; full of guys. Everyone usually sits in a circle and jacks off in the company of other people. Or jacks each other off
We had an epic sploge fest last night. Johnny's hands felt great.
a)Any girl who takes loads of semen up her snatch, down the hatch, in her crack, and on her back. These chicks are down with the creampie be it anal or vaginal.
b)A person who is addicted to being ejaculated in, typically females. Also see whore or slut.
"Hey dude, see that girl? She's fucked everyone I know, and I don't even want to go into how many dicks she has sucked. She is a total sploge sponge!"
