Someone who get's all the shit jobs and is proud of it. Normal humans ("civilians" or cattle) think it is a joke to call someone a grunt but they have no idea.
He can't make that kind of decision, he's just a grunt - no offence.

None taken.

Get the grunt mug.
someone that work's for someone regardless their position in a company. Usually a white collar worker that drinks allot of coffee to get through the day and spends about 6 hours at work on Facebook instead of doing tasks for his company and counts down to Friday every week.

Someone usually in the morning on the highway driving like zombie fighting with traffic.
Tom is such a grunt, his BBM status changes to WHOO TGIF every friday.

Referring to US Marine Corps Infantry personnel. GRUNTS are anyone with the MOS beginning with 03 as in 0311 (Riflemen). The term originating during World War II to abbreviate the term "Ground Reinforcements Untrained," referring to tons of troops being sent to combat with little training. The term has taken on a more affectionate meaning for our killers in the Marine Corps Infantry today.

The term GRUNT also refers to those doing their time commitments and getting out during the Vietnam War; as opposed to Lifers who were career Marines.

The term POG is the opposite meaning "Personnel Other than Grunt"
Army dude: Man you GRUNTS are tough!

Marine GRUNT: Stay out of our way before you catch one between the eyes ya damn Hoo-Ah

If John Wayne was a Marine he'd be a fuckin' GRUNT.

POG: Damn I have so much paper work to do

GRUNT: Stop bitchin' you fuckin' POG

A grunt is a noun first coined in by Yourragegaming who streams on the platform known as twitch to describe someone who is currently watching the stream but is not currently subscribed to the streamer, the grunts are usually presented as the lowest members of twitches social hierarchy because they have the least amount of power and capability. Which is of course because of the fact that the people who are subbed have to pay 5 bucks and therefore valued higher by the streamer because they are the ones getting a percent of the money. In other words the term grunt is used by streamers like YourRage to devalue the people that don’t get him money in order to scam people in to subscribing so YourRage can pretend like they mean more than they actually do in order to scam them out of 5 bucks. Of course this isn’t really surprising, the fact that he turned this word into one of his scam tactics, considering his history .
