“Diggletickle” is an English pseudoword. It doesn’t have actual, real meaning, but a rather more joke-word. It is mostly used as a word to basically spike somebody out of laughter.
Diggletickle itself also has meanings, but it’s rarely used. It can mean “a very silly blunder”, “digging a place by using a tickling-like motion with your fingers”, or “person who uses the said pseudoword a bunch of times”
It can also be used as a nonce-chant.
