Ashley: That guy Derek I slept with last night was horrible. It was like having sex with a field mouse.

rabbit deek syndrome 

Also known as RDS. Essentially, a man who suffers from rabbit deek syndrome has a fairly short penis of disproportionate narrowness. To compensate for this inadequateness, the afflicted subject insists upon short, quick thrusts during intercourse. Thus, the comparison can be made to being hung like and having sex like a rabbit.

Unfortuantely, the guy I dated last year suffered from a severe case of rabbit deek syndrome.
