The act of a very not metal/normal person giving the horns to something that they think is acceptable. Often followed by a severe punch in the face from a metal head if in the vicinity.
Chet: "Cool I got an A- on my math test!" (gives poser horns (however oblivious of them being anything but normal horns) to noone in particular)
The unwanted sound heard on a game show, usually when a bonus round is lost.
On The Price Is Right, when a player loses his or her pricing game, or if there is a double overbid in the Showcase, these are signified by a tuba playing the first four notes of theme music followed by horns playing notes in C, D, and E all at once before pretending to faint. When Drew Carey hosted the show in 2007, an A-sharp note was added with faintly audible drums with the sound remixed in full stereo.
The gesture made with one's hand that represents the Devil or "Horned One" that you see being flashed at heavy metal concerts and an expression among metal heads that indicates enthusiasm for the music. Also a magazine dedicated to the heavy metal lifestyle.
A hand gesture in which the pinky and index fingers are raised. This is different from the American Sign Language gesture for "I Love You" in that the thumb is tucked in; and different from the sign of the evil eye in that the fingers are pointed upwards. Usually used in celebration of something or other.
