The act of being the only one in a group of friends that is not blazing: being on blazewatch.
The blazewatcher either too soft to blaze or knows that his/her buddies will probably end up dead or locked up by the end of the night, and takes them under his wing while they are baked. He/She can be an important entity to any good blazefest.
This term was forged in the depths of Toronto during the inner city drug raids.
Frank: Yo man, we are gonna fuck shit up tonite!
Chris: Yah, thank God we have Mike on blazewatch or this is probably gonna be the last thing I do.
