red top
Nickname of the 150 bhp C20XE Vauxhall/Opel 2.0 litre DOHC car engine, based on the fact that it had a red L-shaped spark plug cover (although some later examples had a black cover, these are still referred to as "red tops" if the cover is L-shaped).
The chav stuck a red top in his clapped-out Nova, and when the tiny brakes and crap suspension couldn't handle the power he ploughed into a coachload of Americans (killing them all, painfully) & landed upside down in a field with a smashed spine, watching the pool of petrol slowly approaching the lit cigarette hanging from the mouth of his decapitated estate slut girlfriend.
