Erection 

When blood flow happens to enlarge the groin.

I came so my erection would disappear.

Erection 

That one thing that always comes on at the wrong place, and the wrong time, or right place wrong time, or vice versa.

Guy: "Hey dude, how was the presentation on uhhhh..."
Dude: "You mean the presentation of the solar system?"
Guy: "Yeah, that presentation, so how'd it go?"
Dude: "Not well, I got an erection in the middle of it."

Erection assassin 

A female with a terrible disposition.

Frank is proud that he no longer has to take viagra. But I think that the credit should go to his new girlfriend. She has an incredibly pleasant disposition and she's not an erection assassin!

Erection Thief 

Someone so monstrously ugly, the sight of their face and/or body is enough to steal your erection and end your wank prematurely should the thought of them enter your mind mid-stroke. Can come in useful when trying to conceal an unwelcome erection.

- I was struggling to hide this massive bonk-on i got at work, but luckily Warty Sue walked into my office. I said Timberrrrr! in my head as i felt it go down.
- She's such an erection thief.
- Yeah. Thank god.

- The other day i was fapping away while looking through my ex's facebook pics, then she had one of her with her friend Brenda. I lost interest.
- She's such an erection thief.
- Yeah. Fat slag.

Erection Detection

When you get a boner with short shorts and your dick comes peeking out the bottom and everyone around can see.

Aaron:"O shit I gotta boner with these little soccer shorts!"

Everyone around looks and can clearly see his penis.

Bystander:"Man, that guy is really struggling with erection detection..."
