A group of fat broads who pass their time by smoking outside of buildings, preferably right in front of the entrance obstructing anyone or anything from getting through. A smucker usually consists of 3 to 4 members. Any group(s) exceeding 4 members is NOT a smucker and can just be considered a larger group or alliance of fat girls.
"Hey dude, did you see that smucker out there?"
"Yeah man, I was 5 minutes late to class because I couldn't walk through that shit."
"Finally, I thought you'd never show up with the pizza."
"Sorry dude, there was a smucker blocking the entrance."
"I wouldn't go out there if I was you."
"Theres a smucker."
"Dammit, I hate those fat bitches.."
