look up any word, like basic bitch:
 
1.
n.

singular: corps (pronounced CORE)

plural: corps (pronounced CORZ)

A military-styled marching music fraternal genre, epitomized by Canadian and American corps sponsored by veterans organizations primarily between the 1920s and the 1970s, and still in existence today. Bugles are bell-front brass instruments with or without horizontal valves or slides used to change pitch, and unlike bands the entire hornline is in the same key, usually G. Drums are marching drums, primarily snares and bass drums. Color guards most closely resemble military honor guards.
You could hear the drum and bugle corps from miles away.
