halfpat
An expatriate who is not being provided a "package" (salary bump, housing allowance, car allowance, home leave, etc.) by his employer, and who perhaps is not even formally employed. Halfpats sometimes earn income as "English teachers" but are primarily engaged in the avoidance of real life in their home country.
