Piss Boner 

A morning erection usually alleviated by urination. Usually dry-humping or twisting around your dick would feel good in this instance. And, when you urinate, you need to do a handstand or pull it down. Even if you do these things, your urine will definitely go everywhere, since morning pisses usually include piss flying everywhere randomly, even disobeying the laws of gravity because of what I can only guess is dick boogers (eye boogers, but in your dick hole).

I had a wicked piss boner this morning.

Ninja Boner

A ninja boner is an erect penis that you must stealthily conceal whilst moving, which involves disguises and clever use of shadow and vegetation.

Often required when the words "Give it a minute" will not save you.

Last night Jen gave me such a ninja boner at the party, I had to creep around the outside of the garden in the dark to get a drink.

hate boner 

1. having an unrelenting, sometimes irrational, hate for something. Very over the top.

2. power tripping and wielding that power, usually fucking you or another person over

3. in usage, can be gauged on a personal scale. ie. footlong, veiny boner= a lot of hate vs. half-mast boner=sort of hate/average dislike.

EXAMPLES:

1. Dude... That Hitler fella had a huge hate boner for the Jews. And the Gypsies. And the Slavs.

2. Person 1: How'd you feel about those questions the prof asked you?

Person 2: Maaaannnn.... They were terrible. That prof has a raging hate boner for me.

3a. I seriously hate that guy. I'm talking veiny, viagra fueled, never-ending hate boner.

3b. Person 1: Seriously, I have a raging hate boner for that douche.

Person 2: Meh, I'm only at half-mast hate boner for him. Closer to that "seeing an ugly chick naked" semi-chub of a hate boner.

An erection you consciously attempt to achieve in order to be polite and/or appreciative to a woman. Typically in response to an unattractive naked woman, or an inartfully executed handjob, it is an attempt to spare her the insult of a flaccid penis.

The girl in the hot tub was pretty fat, but since she'd taken her top off I tried to work up a courtesy boner, you know, to be chivalrous.
