To share one's opinion, idea, or point of view, regardless of whether or not others want to hear it. ("Penn'orth" is a contraction of "pennies' worth.") Primarily heard in UK. I find Jeff's husband a bit trying at times. He always has to add his two penn'orth, even when it's clear he knows nothing about what's being discussed. If I can just add my two penn'orth, I think the staff would really appreciate a bump in their pay, and productivity would increase as a result.
