When used in the context of "pwning a women", this means to ejaculate
sperm on or around her body, primarily the face. The highest
rank of pwning in this sense is premature
ejaculation, or just ejaculation with no warning, completely catching the women by suprise and splooging all over her.
Andy: "Dude, i pwned Yvonne, splooging all over her
tits!"
Mike: "
Lucky! Jessica wouldn't let me pwn her; she made me skeet in the toilet :( "
