pun

v. make a play on words, use words humorously to create several possible meanings

n. play on words, humorous use of words in order to create several possible meanings

A pun (or paronomasia) is a phrase that deliberately exploits confusion between similar words for rhetorical effect, whether humorous or serious. For example, the sentence "the world is perspiring against me" is a pun on the paranoid's motto "the world is conspiring against me", that exploits the similarity between "conspiring" and "perspiring".
