Followbane

A Melodic Death Metal/Black Metal Band originating in Kyoto, Japan. Allthough its very digital, it has an awesome mix of the fast Death Metal sound , with an Orchestra number at the very beginning and throughout the song in the backround. Especially amazing considering the band only has two members

Metalhead 1: Hey you wanna listen to Followbane.

Metalhead 2: Who's that?

Metalhead 1: Best band ever.

Metalhead 2: Even better than Cannibal Corpse?

Metalhead 1: A cow getting it's nuts cut off sounds better than Cannibal Corpse.

Metalhead 2: Yeah your right, put in the CD.

follback 

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!

or

bee: @jazz hey i've followed you, follback please!
jazz: @bee yea done
