Fucked-in Syndrome

Fucked-in syndrome (FIS)

Likened to the condition locked-in syndrome, but when one has done alot of shagging or had a very intense orgasm and it feels that they cannot move their body or function properly, so they just lay there like a dead seal for 20 minutes.
Also linked with postcoital bliss.

(After intense sex session)
Malachy - "I need to go home to let the dogs out for a piss but I can't move, I feel like I have locked-in syndrome.
No I have Fucked-in syndrome!"
Janine - "Hahaha, is there anything I can do?"
Malachy - Please put your tits away, I'm done"
