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 :( "
