Another term used for masturbation. Used as code words amoung friends when in large crowds, at school, in church, ect., as to not let anyone know what they are talking about. The word Skyline refers to the popular car manufactured by Nissan. Derived from the joke "Everytime you masturbate, God kills a Skyline."
Ricky, Elliot, and Brandon never get laid, so they just kill Skylines.
"Dude I feel like Killing Skylines."
