A highly possessive, paranoid and controlling boyfriend or girlfriend who won't let you ever leave their sight, presence nor clutches. They often go through your phone's call logs and messages in search of incriminating evidence to use as justification for shortening your leash.

Get the Guantanamo Bae mug.
Face sitting/riding that is particularly eager, aggressive, or enthusiastic in such a way it parallels waterboarding.

Can refer to either purposeful smothering through out (like a dom/sub context), or a girl having an orgasm so explosive she loses control and unintentionally smothers her boyfriend/girlfriend's face during the lead up to and duration of the orgasm.

The "water" from the waterboarding reference can be either a really wet, creaming pussy, or a girl squirting.
I feel so bad I Guantanamo Bae 'd my boyfriend's face. I just couldn't control it. They say the heart wants what it wants. But damn. I guess the pussy does too.

A person who performs cunnilingus and reliably causes their female partner to squirt into their nasal and oral orifices, thereby simulating being waterboarded.
Ex.: "Go down on me, you'll get that gushy spray like you're getting waterboarded at Guantanamo Bay."

Ex.: "I need a good squirt. Time to call my Guantanamo Bae."
