These symptoms are common. As mentioned before, just tell the doctor the symptoms without trying to medically define them. I had the whole spectrum of word finding and expressing difficulties early on. Now, I only experience the word finding difficulty infrequently. You are doing it right by laughing about it. It lowers your stress level. For me, stress made this cluster of dysfunctions worse.

The doc may suggest speech therapy but in time, this should become less of a problem. Speech therapy just causes more stress as you focus on the symptom.
