x2

A notation added to the end of a word to denote a double meaning.

Note: This is typically a written (as opposed to spoken) expression, and it is usually contained within parentheses.

Sally: On Friday I went to the store to pick up something to eat (x2).

In this case, Sally did indeed get something to eat while at the store, but she also had ulterior motives - perhaps she has a thing for one of the cashiers at the store?
