How to smoke pot in a bedroom and not get caught?

yooo yo no dude, joints waste your weed quicker than anything! don't do it! i mean, get a vitamin water bottle, not a stop and shop or a and p water bottle, they usually are to thin, and make a grav out of it. if you have a relatively small socket lying around or in you dads tool box, take it and (using a knife or sissors or something) make a hole in the top to push the socket in, so its air tight. then at the bottom, on that rimish thing... use your lighter to make a hole so suck in the air thats in the bottle. then pack the weed in the socket, light it as you suck where the hole is, youll see the bottle fill with smoke, and blow it out the window. its always perfect
