Originally from the game Counter Strike, the term refers to parking in a straight line, whereas the double gats are the reference point. Essentially, parking in a straight line gets the visual effect of the double gats.
"Ah dang, did we park like the double gats?"

"Nah, B O'Toole had to screw it up. At least we got out before he got us."
