The Catterpillar 

When you fuck your girlfriend on her back, while she eats out a chick who's on all fours in doggy style position, while that chick sucks some guy's dick.

Dude, you and your girl totally have to do The Catterpillar with me "and Jennie"

The Caterpillar Effect 

The phenomenon experienced on the road when someone decides to slow down their car to look at something of interest on the side of the road. This causes that area of the road to slow down for the following hours. This leads to cars, collectively, mimicking a caterpillar walking.
The phenomenon is easily observed on highways.

MAN! Some jerk decided to stop and look at one of the millions of car crashes a day and it's making everyone feel the Caterpillar Effect for the next hour!

The caterpillar 

The caterpillar is a bizzare sex position mainly practised in western parts of Africa. Much like fisting, it involves one partner inserting both his/her hands up into the vagina of their partner , right up to the wrist. A substantial amount of time must pass for the position to reach its penultimate stage ( typically 9 months ) of the partner opening his hand out as if holding up the gospel to the priest at mass. This symbolises the birth of a butterfly from a caterpillar - symbolising the ex-partner cleansing the vagina of his/her partner giving them permission to be penetrated by a new johnny vinjizzler.

David broke up with Áine last month and he finally gave her the caterpillar yesterday.

the caterpillar 

A dance move.
To 'do the caterpillar', you have to lie sideways on the floor and wiggle your limbs so you go round in a circle. Results in friction burn and giggles.

Owwwwwwwwwwwwwwwww I just did the Caterpillar. That hurt, but hahahaha.
