Types of Laugh

I didnt realize before, but depending of the country, when you talk with someone by Facebook or another social network, you can see that the laugh, is not writting in the same way.. 

Examples:

I use this types of laugh:

jaja --> its like a smile

hahahaha --> more "haha", more funny

wuahahahaha --> extremely funny . (with sounds)

New laugh:
kkkkkkk --> This is my favourite =) ...My imitation: ca ca ca ca ca (like Calamardo's laughing)
huahuahuahua
rsrsrsrsrsrsrs
rs --> like smile

And more...
jajajaja
hehehehe
