Action made my tongue and lips "mimicking" the sound of a cowbell. Usually done profusely to the intro of "(Don't Fear) The Reaper" by Blue Oyster Cult. In homage to the "Cowbell" skit on SNL.
Lysergicac1D: LMAO, i will never be able to listen to "Dont fear the reaper" without "clicking" along
Lysergicac1D: it just came on last.fm
mayafied: so true
Lysergicac1D: and i started clicking
Lysergicac1D: with my tongue
Lysergicac1D: while forming an "O" with my lips.
mayafied: please, the term is 'cowbelling'
