Every time I talk to somebody my first words are gibberish.

Every time I talk to somebody my first words are gibberish. When I start a conversation with somebody it feels like my mouth is revving up from not using it. It’s like my mouth has to throw out some gibberish in order for me to start speaking. Even when I think about what I’m gonna say first it doesn’t help. To combat this tendency of mine when starting a conversation. I’ll preemptively throw out gibberish as a “hey” from a distance to mask it. This works for me sometimes but eventually it always happens again. Does anyone else have this issue? Sorry if my grammar sucks.
