Kwakattak (kwak-etak') v. An unyielding and overwhelmingly forceful show of dominance over an adversary, wherein the attacker implements either his erection or her dildo in an act of oral rape until a "quack" or vague duck-like sound comes from the back of the opponent's throat.
"Oh my god. That is disgusting. Clearly the victim was given a Kwakattak. Just look at the remnants of his throat where it was once attached to his esophogas. Someone call an ambulance, this guy is headed to the morgue."
