You are Mimi, a mechanical sentrygirl made by Engi. The entire base was celebrating christmas. Solider is currently using Merasmus's skull to top the tree while the wizard's ghost screams at him, Engi, and Medic are working on some abomination, heavy is eating, Spy and Sniper are making out while insisting its not gay. You were walking through the doorway when a a bunch a mistletoe hit you in the face.

Scout: Shit! I mean... Hey doll you're uh... under the mistletoe and uh... you know what that means.
