Originating from a conversation on bullshit feminist literature (The Awakening, A Doll's House) in Ms. Winkle's 3rd period AP Literature class on Thursday, January 19th, 2012, between Alec Luis and Raamis Hussein.
2. Uptight people who get shit done...
Alec: "ya, they must be "do-ers"".
Raamis: "Dude that's awesome!"
Alec: "Hell ya, Im gonna enter that shit on Urban Dictionary"!
2Ex. "He gets his shit done..."
"Ya, he's a real do-er..."
"Yes he is, but he's also a virgin..."
Background: People used to commonly refer to the sex act as "doing it." Then they'd say things like, "I did her," "I'm gonna do him tonight," Etc. Hence someone that you would or could do, is a doer.
