1. The act of two women spooning, causing a fork. The fork is created by the two women's hair intertwining. Most common between lesbians. Can get loud if done right.
2. The act of using a fork to hold the end of a joint at a time when it is too small for fingers to hold it. Prevents burning of hands and allows the joint to go on for longer.
1. Those two lesbians were double forking last night. I could hear it.
2. I need to start double forking this joint because I don't want to put it out yet.
