A phrase to describe someone who is cognitively degenerating. Synonym of "going off the deep end". Can have varying degrees of severity.

When a woman bends over, you run up behind her and thrust yourself in her.
She then, normally in alarm, tries to move away, where you then follow her as if you are and annoying object being towed.

To Caravan (verb)
To have a party in a small enclosed space where things WILL get broken, people WILL be sick but a fun time will be had by all.

Changed into a verb from caravan, it means to go on holiday in a caravan. It is probably one of the worst past-times known to man as fun activities include things such as emptying your excrement from the caravan or setting fire to your caravan and others by causing a chip-pan fire.
