Farting so hard that it briefly lifts you up off your seat! :oP
That's certainly an action best captured without words.
i think it says "keep out . loser property" XDD
...but you have to admit. It does speak louder than mere words. It practically Screams! :o)
"showing an engagement ring to ur girlfriend with a smile on ur face and u r standing on ur knees" i think this is the loudest action that speaks
Action vs Talk
For example, changing someone's flat tire versus telling them that you can help them.
Any action means more then words.
That's a nice thought. Plus just reading it made me smile.
