Exemplary goojax include:
-the ones at the bottom of soda/beer cans that you have to tip your head backwards in order to drink.
-the ones that make all the noise when you try to drink them through a straw.
-the ones in the bottom of last night's shot glasses that manage to get all over the outside of the shot glass and make it stick to the table when they dry.
"You know what sucks? When you're trying to drink the goojax and all the ice falls on your face!"
