Flo

Flo is someone who flees from his problem then trying to solve them. Flos are people who have good strategics. Flo has always an idea and a plan what to do no matter how difficult it is. Flos don't try hard for achieving anything in life, in school and in work. Flos are funny, happy and a good friend if you need one. Flo does everything with you no matter how crazy it is. If you go out with your friends don't forget him because he brings the fun in the group.

Do you have a Flo ?

Flo stick

A menthol 100 cigarette you bum off an older female smoker because your habit has left you without the desired type of tobacco after a long night of debauched revelry. Your Good Samaritan of nicotine normally resembles a stereotypically haggard-looking diner waitress, aptly named Flo.

Drinking buddy A: "Dude, do you have any more smokes?"

Drinking buddy B: "No, man, I'm all out, but I was able to bum a Flo stick off that older lady over there."
