Scottish slang. Refers to persons behaviour. Daft, nutter, nuts, silly, "not right in head".
When someone joins a snapped CD with sticky tape and loads it into the CD drive. After a moment of some unhealthy noises, the person looks at you and asks "Do you think it's broken?". This person is commonly referred to as a BAM!
These people exist and yes, he also managed to screw a perfectly good CD drive...
Extremely offensive insult in Scotland, similar to dafty. Use against neds and junkies at your peril. If onejunkie uses it against a fellow junkie it can result in a hilarious verbal battle until one stabs the other, which is equally hilarious.
Usually one junkie baits the other into violent reaction so that he can claim damages in court by saying "Ya fuckin' bam". However, there is actually no space inbetween each word when a junkie uses it. Infact, the faster you can say "Yafuckinbam" the more powerful junkie you are.
