Samulet
Term coined on \\keepaofthecheez]'s livejournal after the events of 5.02 Good God Y'All, in which Castiel took the amulet from Dean, because it will burn hot in God's presence and allow Castiel to find God. The amulet was given to a teenaged Dean by an 8 year old Sam in 3.08 A Very Supernatural Christmas, and it is very important to Dean. This led fans to speculate, that the amulet symbolizes Sam's love for Dean, concluding that Sam's love for Dean is the thing that makes the amulet "burn hot in God's presence". Source
