What is Diesel Stack?
1.
Another word for a comb over.
Derived from the flappy lid thing that tractors and american style lorries used to have over their upright exhausts that flap when the engine is revved hard.
Perfect exponents of the diesel stack= Jackie Charlton the footballer and the Rab C Nesbit character off of the Hamlet cigar adverts
Gerald: Checkout the diesel stack on that guy!!
Arthur: Whoah, Rab C eat your heart out
