lol I do that all the time. Except with a 2 litere. I hate it when Im using my gravity bong, and it blows out the hit. My dad walked in once when I had a 2 litere of smoke, he was like wtf is that? I just took the whole thing, then I gave him a hit. We just caughed and laughed. I like how if you havent smoked any that day, and you do a really big hit, it takes like 5 min to kick in. Its grat cuz you can be not stoned, then if somebody against weed happens to walk in you can just pretend nothing happend then, like 5 min later you're as high as a kite!
