Used as an "ism." Often used to express reactions to unbelievably stupid, random, or anything else worthy of saying Jeekus Lou, because hey, even if it doesn't make sense it still sounds cool.

Also, Jeekus is Jesus, and Lou is his mechanic. And Cal Poly Owns UCSB. That is all

Jeekus Lou Tim! You are so corny!

Tim, Jeekus Lou!
