The Jones test it to test whether you should fuck a girl. Before fucking a girl ask yourself "Can i imagine myself ever having kids with this girl?" If the answer is yes, then and ONLY then can you fuck her.
1."Dude, i fucked this crazy girl and i can't get rid of her now"

2."What the hell, did you not do the Jones test on her first?"
