When little kids swear. Happens at my school, and it's SO loving ANNOYING AAAAA
they don't even know what those mean
also when people talk over eachother and no one ends up listening to eachother, and then they keep repeating what they say until someone responds, ex:
person 1: what is your favorite soap
person 2: what would you do if aliens came
listener: uhh, i guess l'oreal. but blablalbbla
*whilst listener is talking* Person 2: what would you do if aliens came (repeats)
bad example sort of, but i hope you know what i mean
when people become more mature they stop doing that and start listening to people
