John and Bob walk out of geometry class.
John (to Bob): ...and it was like FAIL!
random person: (accidentally bumps into John) I'm sorry!
John: I...wasnt saying that to you...
random person: ....wait, what?
John: lol, I didnt even notice they bumped into me!
bob: and you said fail at the same time xD
John: and they thought I said fail to them
bob: yeah, and it was like...FAIL
john: lol, yeah, a fail within a fail!
(random person walks off)
Bob: yeah, but Im pretty sure that they didnt hear you say fail...
John: really? another fail...

Another geometry student: it's a fractal fail!
