That would punish them as much. They lice with u. Hang around them and their friends to stink then out

Go buy more?

Sneak in another deodorant. In your backpack. Or somewhere they can't find it.

Hide their deodorant until you get yours back

Don't let them take advantage of you like that. I think that's a little abusive of their power. Depriving you of neccessities!?

Your parents must be hippies

or you could purposly stink, like go running and stuff and come back and hang with your parents all day haha

Rub your armpits all over their pillows just before you shower, that'll learn 'em

Just buy some and keep it at school or wherever. Just hide it somewhere out of the house it's not rocket science. And wash of course. Unless you're doing something that makes you sweat ( sports ) you don't really need deodorant, though admittedly some people naturally sweat more than others. Deodorant wipes are convenient and easy to hide and carry around. More so than a can of spray or roll on IME, you can often find them in pocket or travel size packs too . Try those.

i personally dont think regular basis deodorant usage is necessary if you shower at least every other day and dont sweat constantly, you oughta be ok...
