bagamunderia
Irresponsible behavior or foolishness, generally used to describe any kind of nonsense or shenanigans that the speaker does not want to name specifically. (This word is a regional pronunciation of vagabunderia, which refers to acting like a bum or troublemaker).
A couple of old folks find a group of young people hanging out and joking around, and say to them: Stop your bagamunderia.
