me and my friends do a thing called brain busters when the blunt gets smaller and its kinda like what u did but a little less painful. what u do is when the blunt gets about an inch and a half long u put the burning end in your mout making sure u dont burn the inide of your mouth and blow out making the smoke come out the other end and then the other person sniffs the smoke up hard and u can take some real big hits like that.
