a g-spat is the fight that ensues after a woman experiences the hyperemotionality that can sometime accompany g-spot orgasms.
"alice, you shoot your love-juice in my eye and then SLAP me?"
"fuck you, you prick."
"you dont mean that, baby -- this is just a g-spat. I give you the world's best orgasm, and this is how you treat me? should my dope mclovin' skills garner me punishment in lieu of praise? nay!"
"fuck you. i love you. get your finger out of my ass, you faggot."
