In TV Land, whenever a famous musician or actor (or any kind of celebrity really) ventures out in public, there is good chance they will be descended upon by a horde of screaming fans who will pursue, attempting to get their autographs, rip their clothes off, etc. The celebrity will probably find themselves forced to tactics such as hiding in garbage bins or donning ridiculous disguises to escape the Groupie Brigade. Compare Instant Fanclub. Can become an Angry Mob if someone expresses disdain for the focus of the group's adoration. See also: Celeb Crush which can result in Groupie Brigades.
