Note from your boner is when someone feels the need to (often unasked for) express their opinion about someone else's sexual appearance. See also I like small boobs. Making themselves look like a complete fool. These notes are never welcome and completely misguided and make the sender be ignorant and dumb. Even if the intention may have been good.
Imagine a forum discussion about how breast size may hinder sexual attraction. Random individual chimes in with a comment like "I like small boobs". Thinking that their preference somehow would make the other person(s) feel better. But achieving the opposite. Said comment is a note from your boner.

When you take a dookie in a particularly cold environment and the fecal matter freezes on the way out of your rectal cavity, causing you to have a sizeable brown stick protruding from your butt, ergo, a butt boner.

What a demon gets when they make you angry, upset, sad, make you look or feel stupid etc… don’t engage them, ignore, ignore, ignore unless you are into getting dudes off…
He’s weak, get him!!!! Oh yeah, look at him squirm! Here’s where they begin to swarm like vultures or pirañas with boners. Power Rangers version; Demon Boners unite and they form into a Mega Demon Boner

The intense climatic feeling of exhilaration encountered when stimulated beyond arousal of the intellect; a hyper-focused state of mental masturbation.
He / She's got a Brain Boner for it, I can't believe how long he / she's been {watching, reading, listening, etcetera} this.

The time of when you are about to orgasm and you piss at the same time. Accidentally making a demented baby mixed with urine and cum.
So when me and your mom were making love I accidentally boner barfed inside. That's why you were born as you were son.
