no-boner 

A woman/gay man who is sexually off-limits. The restriction is self-imposed.

Includes victims of trauma (eg was recently assaulted), sexually transmissable infection, bro rules (eg your bro's sister but you can't contact him to get permission), psychopathy (eg "sex-is-love" disorder).

From the word form "no-brainer"

Bambi was looking totally hot last night but she was on her rags so it was a total no-boner.

no-boner 

Similar to "no-brainer", when a chick is so fine, you don't even need to think with your wang before you to take her to bed.

jim: i heard you scored with that lainey girl last night, very nice.

bruce: she was lookin' damn fine and making conversation with me, it was a no-boner really.

Something you obviously shouldn't fap to / make you horny.

Bro 1:*beating it to dead animals*
Bro 2: Are those fucking dead animals?! That's an obvious no-boner, bro!

No Boner Day 

On November 30th, the last day of No Nut November, you will not be able to get a boner.

I already failed No Boner Day.

No Boner Bob 

When someone named Bob comes over to your house to bang your hot wife and can’t maintain an erection and satisfy her or finish himself despite repeated attempts.

No boner Bob was quite disappointing. Watching Bob Ross would have been more pleasurable; at least it wasn’t Bob Koss.
