A grumpy person, usually a Physics major in Ivy League universities, who specializes in hiding his emotions behind a tough facial expression, deep blue eyes and occasionally- a mustache.

The main characteristics of the sourpuss are:
1. Anti-freeze laptops

2. The fear of big haired lovely women
3. Avoidance of pass/fail courses
