my parents dont search my room but i enjoy hiding shit and i would tell u great hiding places but it seems more like u need a way to get it OUT of your room so if ur close to the ground, put it out ur window (if ya got one)

if its small enough and strong enough, crotch it (beltline) or if its cold out cuz hole inside of jacket (i cut hole in pocket lining)

i would never bring a bong out of my house tho (but then again not everyone can just smoke in their room)
