The lag a man observes in his girlfriends walking when she sees a turbo charged vehicle (Eg: Lada Niva 1600 Turbo), as she is impressed with the car, which is far superior to her boyfriends shitbox (Eg: Mazda 2), and would like to run off with the driver. A play on the technical term "Turbo Lag" which refers to the time between the accelerator being used, and exhaust gasses creating boost through use of a turbine
1) Ben: Man,i was walking with Shazza the other day and she saw Julian drive past in the Lada Niva 1600 Turbo. She was getting epic Turbo Slag

2) I had doubts about my girlfriend liking me when she was getting really heavy Turbo Slag over Robbo's WRX, and when his blowoff valve went i knew i had lost her
