Pun

A pun (also known as paronomasia) is a figure of speech which consists of a deliberate confusion of similar words or phrases for rhetorical effect, whether humorous or serious. A pun can rely on the assumed equivalency of multiple similar words (homonymy), of different shades of meaning of one word (polysemy), or of a literal meaning with a metaphor.

Unfortunate events

Sometimes, mutually coincidental elements in situations (e.g. 2 situations with similar sounding words) can prompt coinage for a pun. One example can be backronyms and other nonsensically coined words.
