Get the tacklefuck mug.
The uncontrollable urge to jump off of a bedroom dresser and tackling your unsuspecting parter, after sucessfully tackling your partner onto the bed, the process is repeated, but instead of tackling your partner, you must either jump off the dresser and make it into the hole, or jump off play hide the dick.
"Last night i tacklefucked my boyfriend, he was not happy when i was unable to hide the dick."

"I tacklefucked my girlfriend, but she was not happy becuase i made both her nose and pussy bleed."

"I want to tacklefuck."
