Double Deep 

Better than a a Rusty Trombone, it's an enhanced Deep Throat.

1) To perform fellatio (dick-sucking) similar to Deep Throat, where the entire penis up to and including some of the scrotum penetrates into the performer's throat well past the tooth line (usually causing repeated gag reflex to beginners), and then to trigger orgasm, full insertion of finger(s) (the number of fingers (+1 for penis determines the name of the act, i.e., two fingers would be a Triple Deep) into performee's ass sets off the mighty, uncontrollable finale'. (Sometimes variations including gentle scrotum-sucking by performer, enhanced by alternating stuffing of a nut into mouth opening not more than what would cause a breathing restriction is said to enhance the eroticism level for both participants);

"Dude, my #1 squeeze insisted she Double Deep me last night. It was awesome,...bigtime. Way better that her best Rusty Trombone has ever been! Whoa. I still tingle!"

Deep Sea Double 

When a woman is vaginally penetrated, in an aggressive manner, by two penises at the same time. Similar to a vaginal Parkering. It is distinguishable from double vaginal by the aggressive manner in which it is performed.

Kyle and I met this hot chick at the bar, went back to her place and gave her a Deep Sea Double.

double chin deepthroater 

When a person's neck and jawline is completely sagging from deepthroating a cock. Usually found on pedophiles as they carry too much weight promoting pedophilia, as nobody wants to have sex with an obese partner. Straight men usually get one. They obviously suck cock in secret (as their sagging jawline indicates).

Holy crap, that pedophile with a double chin deepthroater neck has the nerve to care about posture. How could posture be more important than weight.

doubledeep

Brown people who work off commission at stores like Futureshop and A&B sound - instead of helping out one customer at a time - they will bounce from customer to customer trying to maximize their profit. Hence 'Double'-deep.

"Fuck, Gurpreet is such a doubledeep, he totally jacked my sale".

"Rahul needs to learn to stick to one customer at a time, that dude is such a doubledeep".
