paint thinner
slang Very strong alcohol, especially that which is very unpleasant or of very poor quality. Ugh, what's this horrible paint thinner we're drinking? Couldn't you have ponied up the dough for something just a little bit nicer? Up this far north, the only booze we get is paint thinner. Does the trick though!
