follow-back. On twitter when you see something as 'follback' it means follow back. When someone followed you on twitter and he/she said 'follback' it means he/she wanted you to follow him/her also. Usually you don't know these people, they just want to get more followers. Most of them are fucking nolifers.
Megan tweets: @rosie yo follow me, i will follback
rosie tweets: @megan no way, i don't need it. get a life!
The feedback one gets from people who tried food prepared by them. Can be both positive and negative. Or simply confusing. Depends greatly on the feedback-giving person. And, of course, on the dish.
April: I love your chocolate cake. Especially the frosting... and the cute, little sugary flowers you put on top...
Maya: Well, thank you for your foodback.
Lots of feedback. This could be multiple pieces of feedback to the same person or entity (1:N), or multiple pieces of feedback across multiple people or entities (N:N)
Ruler of Lake Titicaca. Rumored to have a bunghole that gets very angry if it does not receive toilet paper. Cornholio the Great is often seen walking around with his shirt over his head and his hands in the air, chanting songs about his power, and his bunghole.
"I am Cornholio! You do not want to face the wrath of my bunghole, for I need TP!"
Butthead: Shut up, Beavis! (uh huh huh huh)
Beavis: Um, okay. (heh heh heh heh).
