Bionic Seahorse 

An act of sex where the man pulls his legs behind his head and puts his penis in between them so it juts outward. Then the woman rides the penis until she has an orgasm.

Man: Hey baby, you wanna bang?
Woman: Eh, what can you do?
Man: I can pull off the bionic seahorse
Woman: Oh my goodness, lets bang right here in the bar

hung like a seahorse 

A phrase used as an insult from one to another.

The receiving end of the insult must be male otherwise it wouldn't make any sense and that person would automatically win the insult battle.

The exact opposite of being "hung like a horse".

Guy#1: "Dude, Shut-up I'm hung like a horse!"

Person#1: "Yeah... hung like a seahorse!!!"

Person#1: "HAHAHAHA I win one to nothin!!!"

bionicle seahorse

A bionicle seahorse is when a girl lays on her back and uses her knees to make fart noises, while her sexual partner engages in sexual acts on the back side of her knee, i.e. the fart center on the leg. Then the girl stands on her head and delivers a foot job, usually with a lot of force.

"Man that bionicle seahorse left my meat sack all red and tender!

She was knee farting everywhere!"

Italian Seahorse 

The sexual act where, after making passionate love to his partner from behind and is about to finish, the man leap frogs onto his partner's back and blows a load all over the back of their head.

When he was almost fucking his girlfriend, Joe hopped on her back and gave her the old Italian Seahorse. Needless to say, she was pretty pissed.
