Leaving System Of A Down on shuffle can be a risky maneuver depending on the company youre keeping. At best youll get a few odd looks from non-fan friends, at worst your grandmother will have a heart attack. There are a couple System songs with bizarre, dirty lyrics, but one of the most striking is Cigaro, which begins with the line:
My cock is much bigger than yours / My cock can walk right through the door / With a feeling so pure / Its got you screaming back for more
Theres just no coming back from lyrics like that at a family barbecue.
