hehe haha heihei

In English, when we laugh you can say a lot of things. the most common two are: lol (laugh out loud) & hahaha others are; hehe hoho (this can mean a kind of 'sarcastic' laugh) mwahaha (this is mostly mistaken for 'evil laughter') bwahaha baha teehee (giggling) rofl ("roll on floor laughing", used for when you're laughing a lot) lmfao ("laugh my f*cking a** off" also used for when you're laughing a lot.) roflmao (rofl + lmfao, use when you're REALLY laughing alot!) xD (It's really a face, but it also resembles laughter)

it is funny question i liked it but actually there are a lot of ways to write laughter according to different countries i think. but the common one is "lol" and i think it is abbreviation of "laugh out loudly"
