look up any word, like cunt:
 
1.
When at a club,dance,etc. and the music is blasting in everyone's ears and a few people are grinding(or otherwise aggressive dance) causes everyone else to start grinding,etc and/or become very horny.

Very similar to the rabbit nature of rabbits who see other rabbits mating and then join in.
Mike and Jessica caused a Rabbit effect at the homecoming dance last night, now their both suspended.
