Terminology used to describe the state of a boner having been re-adjusted to be concealed underneath the belt. Essential for walking out of class without pole-vaulting yourself into the hallway. Also known as a "stealth boner".
daaamnnn, I thought I had my belt boner in place when I went to give the presentation, but after a few minutes everyone started throwing spitballs at my crotch for some reason and then I came in my pants and everyone hated me

Something you say when a girl does something sexy that gives you a boner. You usually say it in front of her face but at a volume she can't here you.
Girl: Tonight I'm going to get Tipsy, you should join me in my bed.
Boy: Boner Achieved. :)
Girl: What?
Boy: Uhhh nothing!
Boy: Boner Achieved. :)
Girl: What?
Boy: Uhhh nothing!

When you see something so horrific, such as a disgusting girl/guy, it makes you penis want to go back inside of your body. A reverse-boner is rare and the sight you must see to induce a reverse-boner is beyond scarring. You will want to cry when you see the object or human that makes you want a reverse-boner.
Example 1
Guy 1: "Dude did you see Sarah Jessica Parker in her new movie????"
Guy 2: "Yeah bro she gave me a reverse-boner"
