To bugger, to sodomise. In Russian prison slang and underworld culture, петух is the lowest caste of inmates, subjected to systemic sexual abuse and degradation. The phrase functions as a brutal, crude euphemism for committing an act of anal sex upon someone, typically in a dominant, punitive, or non-consensual context.
Поштопать петуха — совершить акт мужеложства в качестве активного партнёра.
To stomp the rooster — to commit an act of sodomy as the active partner.
