disco strangler 

Someone commonly found at a club that could potentially sabotage someone's experience; "love them and leave them", as they say. The club being their "natural habitat", the disco strangler acts as a predator hunting prey, or a partner.

Uh oh, she's dancing with the disco strangler.
The disco strangler got me and now I can't go back.
