Selipnir 

A dude with a monster dong who is mediocre at Bloodborne.

Did you see Selipnir in the locker room? That thing was banging around everywhere. After he toweled off he went and did a quick Bloodborne speedrun.
So anyways my girl left me for a Selipnir. Third one. Wanna get drunk and cry about our tiny peckers?
