Short-hand for the Ontario Hockey League. This is the testing grounds for North America's best and brightest NHL potentials. Popular high-school girls are magnetically attracted to the male players for no clear reason other than the fact that they play hockey in the O. These girls often travel great distances to attend hockey games and surrender all human contact with their peers.
This "brain-drain" of popular, good-looking girls from high-schools is a hurdle for anyone wishing to go out with the "hot girl."
Person 1: "Oh my God, Candy is so hot, I want to take her out and get her drunk. Then she will love me and I will be accepted as a human being."
Person 2: "Sorry bud, shes going out with a guy in the OHL. You're only going to get sweet, slow hand love until you realize that hot girls only go out with guys in the O."
It origins from lol. People say lololololol (as lol many times) and sometimes they start with o, "ololololol"
The ol has been called ohl cause of the way it is pronounced.
It is also being used as nothing.
omg he's a noob, ohl.
