1. A person not yet a resident of an institution/ household but instead a "lurker;" Someone who is a temporary arrival.

2. A person that uses a feature on ROBLOX to either:

A. Try out Roblox as a completely benign player (Rare)

B. Act as a noob and delete people's creations as well as Teamkilling ("Friendly fire")

The latter is the reason why a good proportion of Roblox's elitists wish to restrict or even remove the Guest feature altogether.
1. Man1: Damn those fuckers! They took my tea again without asking!

Man2: Those guests must leave if they don't act politely.

2. NoobOnRoblox: Cumz onz! Fux y@ur cr3@ation! -Deletes many things like hell-

ProperUser: F*** you! -Reports using the Roblox Report feature which rarely works on guests as they are temorary "accounts"-

The technical definition is a person who visits the disney theme parks. But it has a more subtle definition that is more accurate.

Generally Under-educated Egotistical Stupid Tourists
The way the guest comes up to the cast members who work for Disney and demand things that are not available or they perform acts that are unsafe to themselves of others and then complain when the cast member asks them nicely to stop for their safety. (for example: slacking their seat belts on tower of terror even when the cast member has told them not to.... Also how the Annual Pass Holders think they know the attraction better than the people that actually work there every day.
