a round seal, often made of neoprene or some other compressible "rubber-like" compound, that is an industrial part.Looks like the part of a condom that unrolls before you actually unroll it. Can be used as a cock ringif you get the right size
"My buddy's a mechanic, I went thru his box of assorted O rings and found the size I can use as a cock ring. Nancii's gonna beg for mercy tonite !"

use your phone to record a girl orgasming while you're having sex with her, then set that recording as her personal ringtone when she calls you.
<your phone rings>
friend - "WTF? that sounds like theresa, but what's happening to her?"
you - "oh, that's theresa's o ring"

1. (slang) sphincter
2. (normal) a rubbery gasket used to seal a connection between two pipes. The o-ring is squished between two flanges, forming an air-tight seal.
Don't push too hard or you'll bust your o-ring.
