in your bowl. then light. anywhere you feel safe, possibly in a sock for a while. or if you have a ps2, put it in the stash place in the back(only older ps2)
get a deoderent stick and spin the deoterant out and stick it in the then put the thingy back in ( sorry if its a little vague )
everyone listed really good places, mine is more for if you're at someone else's house (like relatives) or always about to go somewhere or some shit like that: yeah, you can take a small piece of fabric and make it into a pocket and staple/safety pin it to the inside of the front of your pants (where your cock is usually kept) and stick your stash in there. the pocket is optional tho, nowadays i normally just safety pin my sac of weed to the inside of the front of my pants or bra.
