A totally coull way to give someone a kiss, when you can't any other way. Seriously. Give it a try. No joke.

Good times to use 'mwah' include, but are not limited to:
> when you're online
> while sms-ing.
> when you're on the phone
> while playing tennis
> while practicing tenor saxophone
> while having lunch
> whilst listening to music:
> classical
> rock
> indie
> house
> metal
> jazz
> opera
> ...
> when on a plane
> when carrying fruit
> whilst jumping
> when eating a muffin
> when under arrest
> when climbing a mountain
> when having dinner with the queen

Yup. Those are pretty much the best times to use it. But it works fairly well the rest of the time, too.
