A person who preforms manual labor in the oilfields, typically in a drilling capacity. Can be onshore or offshore. Personnel who work in the oilfields but are not involved with drilling are not true
roughnecks.
Roughnecks are know for their perverted
sense of humor, frequent cussing, high pay, and as being some of the hardest working folks you'll ever know. Roughnecks can be oilfield-trash but not all of them are.
