The charcoal-grey/brown dirt that accumulates under one's fingernails within approximately two hours of ingesting a class A drug.
Tripdirt would even manage to accumulate under the fingernails of a fully scrubbed-up neuro-surgeon (had he taken class A drugs).
I can't go for the interview looking like like this. If the interviewer sees my tripdirt, he'll know I've spent most of the night off my tits in a field.
