No Reason Boner. When a stupid 12-year-old pops a chubby, and its really embarrassing for them, because no one can see the bulge cos they haven't hit puberty yet. And its really annoying when they just say NRB, like its a great joke, over and over and over again.
Stupid kid No.1: NRB
<<Stupid Kids erupt in giggles, not gut laughs cos their balls haven't dropped yet>>
Stupid Kid, like No.6: NRB.
<More annoying giggling>>

NRB

(No reason boner) This occurs when you get a hard on out of nowhere. You may be sitting in class or hanging with your friends and BAM you have a huge hardon out of nowhere, and then your friend call you gay and leave you. A good way to get rid of these is think about something gross, like your grandma butt ass naked.
