A woman who after performing fellatio, unbeknownst to the man, spits his semen into a turkey baster and deposits it in her womb. After 9 fruitful months gives birth to the humbasted baby and then often proceeds to sue for childsupport.
He didn't even know the chick and she gave him a blowy in the alley behind the bar and turkey basted herself with it. Watch out for that humbaster.
