A Martin
To do a Martin is to get stuck while deviating, for no apparent reason, from a well-marked, solid road; it is not to be confused with a Perko, which is to get stuck while on an imaginary road or a Lawrence, which is to get stuck on no road at all.
An example:

This picture shows a typical Martin

the hapless victim,
showing no concern for his own well-being
or potential damage to his vehicle,
especially the clutch]
