How do people find him hot. Anyway, Jeff the killer is 31-year-old man with at least 30 Million fangirls/fanboys. He was born on June 2nd of 1990 and murdered his Mother, Father, and injured his little brother very badly when he was 13.

Literally, one who is profficient in the tecktonik, however, it is often used to mean anyone who dresses in a gangster-like manner, yet isn't as cool as they "talk" themselves up to be. Put simply, a try-hard hip-hop bitch.

This particularly applies to people in France, and the surrounding area.
