Meet And Greet convention where internet celebs meet their fans and travel to hotels and venues to perform.

A convention/tour of Vine famous boys. Usually including Cameron Dallas, Nash Grier, Carter Reynolds, Jack johnson, Jack Gilinsky, Taylor Caniff, Shawn Mendes, Aaron Carpenter, and Matt Espinosa.

Scientific name for a group of cancer cells.

A group of untalented, immature, obnoxious and disruptive teenage boys who deem themselves "internet celebrities." This band of misfits travels across the country to "perform" their acts at hotels and various venues. These acts include: throwing water on each other, singing off key, jumping up and down and riding on hotel luggage carts. People actually pay to see this shit. The "Magcon Tour" has a strong, avid, cult-like following of horny, desperate and ditsy teenage girls who are absolutely infatuated with these boys. After the show, the boys usually go up to their hotel room and proceed to destroy it and post it on the internet.

I would honestly be extremely surprised if these kids are still "famous" in six months.
