Rainbow Trouser Trout 

The Rainbow Trouser Trout... Put on your favorite episode of River monsters and pound two bowls of Fruity Pebbles. As soon as your wife complains about the show, vomit all over your dick and violently shove it down her throat whilst screaming "fish on" and pulling up on your dick like a fishing rod.

If this bitch keeps running her pole holder, she's gonna end up catching a Rainbow Trouser Trout.
