The work of trying to be funny on April first, but results in you getting your ass beat, dumped by the gf/bf, or making your self seem like a total dumbass. You can find 2 meanings because of this:1) When a total dickhead attempts to play an April Fool's joke for you after midday from the 1st April, or any other period of the year. This becomes obvious as soon as the dickhead claims 'April Fools!' after wanting to deceive you.2) Anyone that attempts to play an April Fool's laugh on you, however see right through it, and to top things off, they state 'April Fools!' anyway, which is just foolish.
