Basically everything. Telling a joke that I love. Showing excitement for something I love. Doing my silly voices; especially my batman and girl voice. Taking my shirt off. And so much more. Damn social anxiety and confidence issues.
The best way I can describe it is by using the back of your tongue to compress the beck of your throat. Kind of like just before you cough. Holding it in that position is how I do the girl voice

Silly voices are the best, they'll always enjoyed by your (future) kids/nieces/nephews/etc.
Keep practicing your craft, you'll find an appreciative audience sooner or later :)
