Sick Lighter, Bro! 

A phrase used to mock middle-school kids (or any group of people for that matter) who find themselves enthralled by something dumb, in this case, a lighter.

This can be applied to anything, however, such as a group of kids showing off to each other.

Two friends pass a group of 8th-grade faggots taking turns admiring their new lighter.

Friend one to group of kids: "Sick lighter, bro!"
