Sore Looser
According to the dictionary, looser is an adjective that describes the state of something being not firmly in place or detached. You can use it to describe the state of two lug nuts of different states of tightness. One lug nut is looser than the other, for instance.
But according to the internationally recognized Urban Dictionary, a looser is a loser who has no idea how to spell the word loser. For instance, take a look at this texter, who was given a second chance to spell loser correctly but failed. We don’t usually nitpick when people misspell things, but this one really got under our skin.
