An ambiguous letter, halfway between a T and an F, used in a juvenile attempt to cheat a true/false test.

Briefly, "the realization that each random passerby is living a life as vivid and complex as your own." Originally from the Dictionary of Obscure Sorrows, which has a lot more beautiful neologism definitions like this you might enjoy.

Something that is both funny and true.

When you're typing the word true and you accidently hit the F instead of the T.

Frue means true :)
