Castoning

When you say someone is castoning, that person goes through 20 different names before remembering the other person's actual name. Also right before they get it right they grunt loudly

Person 1: Hey Lucian, uhhh, George, uhhh, Jar, uhhhh, Teius *GHAAAAAAAAA* , Nicu.

Person 2: What the hell was that.
Person 1: Oh I was just castoning
