a person or task requiring an unjustified amount of work and attention. Usually in the work place when referring to a client, co-worker or boss.
When used in conversation, the word stealthily sounds like hassle.
Co-worker: My boss just made me pull all the client files from last year and re-file them in chronological order rather than alphabetical.
Me: What a hasshole.
Co-Worker: Yeah, tell me about it...wait, what?
Me: Don't worry about it. Can you get me the Alvarez file from last year?
A hassel-hogg is a man that plays football (specifically a linemen). He goes crazy on the field and talks trash to other opponents. Hassle-hoggs love to eat their other opponents also. The hassle hogg of the year is Joseph Norcia.
