i always use BIC bitch. either fucking green, red, black (not dark gray, there is a rare black one) too many people have orange ones...you can get confused. yellow ones are pretty rare....and nobody will mix it up. light blue ones just dont do it for me....they just have always seemed a little bit weaker than the other ones. white is bad luck. (they also have a off-white cream color kinda one....its not bad luck.) its kinda weird but i can say that i ahve actually been caught with a white lighter on me lots of times.....yeah weird.
