1 definition by Poetic Justice
Someone who smokes excessive amounts of marijuana using a bong. Usually these people hang around in groups of bongheads (often in a garage or a very unclean welfare house). The conversation in a house full of bongheads is usually about either mind numbing boring shit with no purpose or if they are intelligent bongheads the conversation will vary between aliens and star wars.
