Gay slang. Describes the phenomenon where the anal sphincter tightens reflexively and involuntarily in response to penetration, holding the inserted object tightly, often in the context of sexual play. Where the penetrator is using part of the body and receives an injury, this is referred to as being 'bitten'.
