What phrase are you fed up of seeing in the forums?

[StokedUp]

This>>> "I could care less about....."
Because the actual phrase is "I COULDNT care less"
When using the phrase your basically saying you don't care about said something at all, that your care for it couldn't be any lower, it's at its lowest so you couldn't care any less for it. By saying you could care less, your saying you actually care for said some still so you could care less for it.
