to pull a creeper is to tell lies to people who dont like you to try and impress them. These lies will most often be very unbielevable, possibly about family members dying or large killing cults. A person who pulls creepers most usually give themselves lame nick-names.

there used to be a killing cult of 500 goths in grantham, but no-one knew about them or saw them because they were on holiday from New York, this is a creeper
