Four Hour Erection

A side-effect of male-enhancement medicine. Results in extreme discomfort if you are wearing especially tight pants. Not that any one person writing any definitions specifically has done that. Extremely obvious no matter what clothes you're wearing. Can be spotted from long distances.

Sexually inept man: Damn, I've had this erection for four hours!
Me: You shouldn't have taken Viagra. Your pants look like a tent at a circus.
SIM: Man, I hate four hour erections

one-way erection

A particularly raging penile erection that you feel will not subside of its own accord, but rather requires ejaculation in order to deflate. A one-way erection has path-dependance unlike a typical erection.

Hey baby, this is a one-way erection. You'd better sort that out because I don't want to end up with blue balls.

inconvenient erection

Last week I got an inconvenient erection in front of Laura's Mom but luckily I was able to use the classic hands on my lap to cover it.
