Humiliation
From TF2 Wiki
Humiliation occurs following a victory. During humiliation, all players on the victorious side receive a 10% increase to their speed and all attacks become critical hits for the purpose of hunting down any surviving opponents unlucky enough to stand in their way (front stabs with the knife appear as though they crit but don't actually do any additional damage). Players on the victorious side are also able to enter enemy resupply areas, though they are still restricted from entering respawn areas in some cases.
During humiliation, the losing side moves slightly slower and is unable to attack or use any secondary abilities, though some weapons fired before the victory may still kill during this time (fire, grenades, and rockets). The losing team's sentry guns are also deactivated. Spies on the losing team retain their disguises if they were wearing them during the winning capture, although they are able to use the 'last disguise' button. A Pyro or a Heavy on the losing team may still kill players on the winning team with their taunt attacks, although these will not count towards the achievements OMGWTFBBQ or Show Trial.
