gater 

Named after the district, a gater is a person who is a recurrent visitor of the bars found in the Northgate district in College Station, Texas. They're often the most ardent defenders of A&M's traditions, despite last coming to class during syllabus week. Commonly 18-24, they are not required to be enrolled in Texas A&M. Often, many of them claim to be Aggies when they're in fact taking classes at RELLIS or Blinn.

James: "Did you finish your part of the group project last night?"
John: "Yeah, but I got assigned with a gater and he hasn't opened the Google Doc since last Sunday. If you go on his Snapchat story, it's just shaky videos of him at Northgate last night."
