When you really just want to say "Fuck" but its an inappropriate time or place.

Eff

They literally said the F word on dictionary.com in the definition of this word

Guy 1: Searches "Eff" on the dictionary, but not the urban dictionary.
Guy 1's mom: What'tcha doing?
Guy 1: Oh, just searching Eff.
Mom: Hey, why does that say the F word?
Guy 1: Oh, why does it act-
Mom: You're getting grounded for searching the F word!
Guy: But-
Mom: This is final.
