A person who, often mentally ill, enjoys the sweet and delightful side effects of either Clonazepam (Klonopin), Alprazolam (Xanax), Diazepam (Valium) or Lorazpepam (Ativan) also known as 'the 'pams'.

Side effects reported include laughter and a feeling of being 'high'. These drugs are highly addictive but also highly sought after by the normal population making a good income for the mental.
Psychiatrist: And thus I prescribe you a 'pam!

Mental: *takes the pam* Gee thanks doc! I feel high as a fricken kite! I'm gonna end up a right pamhead!

Psychiatrist: good, now go and sell them for bare dolla. I'll turn a blind eye if you promise me money
