When a joke lacks depth or multiple dimensions but you still can't help it but laugh. The joke often contains stereotypical, dorky, and/or unfiltered humor and references.

This is not to be confused with a non-dimensional joke, which results in complete silence and awkwardness.

In a text or chat context, it is often shortened as '1D'.
Patrick: Do you know why his nickname is TT?
Kory: Why?
Patrick: Because his length and width are the same -- like a TatorTot!
Both: HAHA!
Kory: Such a 1-dimensional joke, bro!
