beat her ass 'n be like "Yo a mofo don't play a fool like dat, homie!" *BOW!*

Nahh, hopefully it'll turn up, shit gets lost sometimes. If not...just let it be, maybe set up another situation if you really wanna find out if you can really trust her. Like leave some weed somewhere 'n make sure she sees it then be like "damn I thought I brought a joint over here but I guess I lost it" or something, but better than that, thats just an example.
