A merv is when you are banging a girl from behind and when you cum you pull out a dead rat from under the pillow and slap her with it and yell " you rat bastard!"
I found a dead rat on the road so I took it home and his it under the pillow. Later I was banging my girl merv style and as I blew my load I pulled out the rat and slapped her in the back of the head and yelled " you rat bastard!"
Swervin Mervin six feet tall. Gonna get gonna fall. Got a while in his head, but he is not dead. So fast so quick gonna kick your dick. A god in the paint, will make you faint. Used to sexually harass but now he is trashed
A guy from Port Coquitlam who enjoys the site of pre-pubescent girls a little too much. Known to stroke himself outside of elementary schools in the greater Vancouver area. Children in the area have given him the nickname "Merv the Perv" since he looks much more like a Merv than his real name of Corey ("the Perv" part of the nickname is self-explanatory).
Little girl 1: Isn't that Merv the Perv over there sitting in his car with his hand in his pants staring at us?
Little girl 2: Oh no! Tell Mr. Johnson to call the police. I think Corey is up to his old tricks again!
Little girl 1: This is PoCo...the police don't care.
