The act of vigorously shoving your dick into someone's bum,

A very hyper dog that can also be your best friend in the world!

To grab your girlfriends anus hair between your teeth and shake your head vigorously. Just like a Jack Russell wrestling with a piece of rope.

Similiar to motorboating but rectal and hairy.

Jack russell is a crazy small breed of the Gray wolf, if you hit him, he will hit you back.
In the picture above (or bellow, i dunno) you can see a dead jack russell, for a living jack russell never rest.

the most hyper annoying crazy dogs in the world. well sometimes lol they are very fast . sometimes they can be the funnyest dogs ever . but also ur best bud :)

An annoying little breed of dog created by a English Parson (similar to a minister or priest) named Jack Russell in the mid-1800's. The dogs are hyper and do not settle down until 7 or 8 years old. They are fearless but reckless and usually die unnatural deaths (ie. runover by cars, shot, beaten by bigger dogs or bears) due to their inability to stop being annoying. Usually, dumbass owner's name their own dog "Jack" or "Russell" or if female, "Jackie". This is annoying too and should be greatly discouraged!
