literally: 'testicles', 'gonads'.(posted 10010 days ago)colloquially: used as an interjection, especially by the audience at stand-up comedy. can be used to question the truth or value of a statement or activity, as in "that's bollocks, that is" - possibly interchangable with BS in that way. Ho hum. Not a great explanation, but I hope it suffices. :o)
