Nubbin 

The act of have sex while your penis is still in your underwear. Any type of penetration where you leave your erection in your boxers.

You go to a sporting event, you meet some rando, you dont have a condom and you don't want your love stick to get sludged on so, you NUBB it. NUBBIN is not a sport it is a pleasure.

"I just totally NUBBED some girl!"

Nubbin 

It isn’t just for third nipples anymore. The term nubbin can be used to describe a variety of small objects or people like your friend “No Limb Jim”, or your iPhone charger’s wall connector, or a little bit of rice left in your beard from last night’s shame-filled sushi, sake, and karaoke night. Heck, the polite little man who DJ’ed karaoke could even be described as a nubbin. Used as a term of endearment or descriptive pronoun, Nubbin is your new backup anytime the real word slips your mind.

“Dawww, what a cute little nubbin.”
“Has anyone seen my nubbin? I need to charge my phone.”
