a black plastic ring that slips in between a paintball guns c02 tanks, and where it screws into the gun. Acts as a "seal" so no c02 escapes.

Another term for cock ring. A ring of either rubber or leather that is placed around the scrotum and penis to constrict the flow of blood to the male organ, allowing for larger, longer-lasting erections and more intense orgasms. Also worn to make the male pubic region stand out better, making the bulge in one's pants more pronounced so that other men think you have a bigger package.
I used a rubber o-ring that was too tight and my boner wouldn't go down. Now I can't get the fucking thing off.

On gothic jewelry, such as bondage cuffs and collars, the O-ring is the round ring (as opposed to the D-shaped D-ring). It signifies sexual submissiveness.
If a guy sees me in my red collar with the O-ring, he will know without speaking to me what I like ;-)
