When you keep the cock ring on for too long and your wangus starts to turn green.
Yooo I heard you whacked off a little too long last night and got that Mint Hot Dog!
to say something is really good, to add assertivness and empysism. mainly used by young drunken lads to convey their agggreement with something
example: "i am mint dog" "that birds tits are mint dog"
