Timfusal 

A predetermined depth not actual refusal, set by the current drillers imaginary idea of what refusal actually is. Only true and accurate to the aforementioned driller, not an actual refusal by the laws of physics. Typically used by drillers named Tim or often referred to as Schmoopy.

The client asked if we hit refusal, I had to admit it was only Timfusal.
