yes it is a fall out boy cd (one of the best) but it does have another meaning.
see when it came out everyone was like "hey go get fuct!".
which is extremely funny i think. well you know the kids these days using "fucking" and language like that, well theres a new way to explain your anger or mishap.
just replace from under the cork tree with fucking and there you go!
