Boom-Bah-Rae-Lee Spear 

A toasting term used to express merriment, cheer and good health. Signifying that all is well between friends and cultures. As used in the song "Boom-bah-rae-lee Polka (A Polish, German, Russian, Cajun, Bluegrass, Rap, Pub Song)"

As two bearded soon to be enibriated fellows toast one another while clanking their steins they shout, "Boom-bah-rae-lee, Boom-bah-rae-lee, boom-bah-rae-lee spear my good man!"
