F is an evil letter from Alphabet Lore. A series by Mike Salcedo. F turned evil because of a backstory where L and O make him spell a bad word and everyone accused him. N didn’t stand up to him because he is a coward (not really). That all changed in the epilogue when N actually stood up for him.

Get the Fmug. f squared has a simple definition, albiet very offensive once everybody learns what it means. f squared stands for two f words, the first being fuckin' and the second being fag or faggot.
