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 :( "
