Ah ok. Where I'm from an Irish Car Bomb is Guinness + vodka.
The vodka curdles the Guinness in 13 seconds, turning it into lumpy foam. Hence the "car bomb" reference - you've got 13 seconds to get rid of it or you're fucked.
It's hardly only an

The reference in the name "Irish Car Bomb" is to the IRA who did -wait for it- car bombings as a ter-blah blah blah I'd give you a history lesson but I can't be bothered.
My point is essentially that it was all Irish and could probably kill you, hence the similarity and the name.
Also, what quantities of vodka to guinness?
