beat (one's) gums(redirected from beat my gums)
beat (one's) gums
To talk repeatedly and/or lengthily but without impact. I constantly beat my gums about dirty dishes in the sink, and the kids still never clean up after themselves!
beat one's gums
to waste time talking a great deal without results. (As if one were toothless.) I'm tired of beating my gums about this over and over. You're just beating your gums. No one is listening.
