A male is on top of a female having sex when a group of people rush into the room to startle them. The male tries to stay on the female for eight seconds while she is trying to get up. Just like riding a bull, hence the name rowdy cowboy.

getting so drunk you cant see, getting naked except for shoes, stick on moustoch and cowboy hat, then run round terrorising everyone/everything with your cock, but never be nasty, you must be polite and charming.
'yeeeee-------haaaa! ha pretty girl its rowdy cowboy time, what a lovley smile', then wipe your dick on her dress!
