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