Whimsical

Convincing myself may be harder than telling you that games should be fun.
Playing funny moves is one good way to keep things whimsical. I find this practice helps my skills by causing me to play situations and positions that would not otherwise be familiar. Playing whimsically can also help keep your play unpredictable which is very helpful in many games.

Love the way a talented New York park chess hustler can rap out a line of talk, better even than the moves they are playing-- this is partly why people keep coming back, wallets open.
Professional game players should consider developing their social skills and humor to make things funner for themselves and opponents. Of course if you a pro bridge player this will not be allowed in tournament situations.
Social players who want games to be more entertaining can also choose some whimsical games to start with, Apples to Apples, Pictionary, Twister and and Liars Poker, are just a few of the fun games. If this all fails just add the word "strip" to any game and whimsy will be had by all.
