Everytime I've sung along to it I've said 'sh1t' but Sambo-Chris' explanation seems good enough.
On the radio and album version (I think) of Teenage Dirtbag by Wheetus; 'd1ck', 'gun' and '@ss' are bleeped out. Now I can understand 'd1ck' and '@ss' but why 'gun'? I don't know anyone that gets offended by "...he brings a gun to school,"
Sambo-Chris: what was that 'Battle of the Bons'?
