typing LOL does kinda suck sometimes, specially if the joke Really made you Laugh Out loud, I feel I have to actually spell it if it made me laugh out loud for real,
so yes, it sucks and yes you are obligated, unless you say something else like LMAO or ROFL, which are just as stupid,
I like Hahahahaha
but I love the smileys, the smileys are awesome,
Yea, its like who's laziest? Using acronym lazy like LOL or smiley lazy like ?
Its a wonderful world, cough lazy cough, we live in now a days. At least we're not using flame on or something, LOL. What will people do without the internet? Word is bond!!!! LOL.
Being "obligated" to LOL is like clicking Like on FB so that you get likes for your posts in return. I hate when people 'Over-LOL' all the time and for every second post they'll either use or (that too in multiples!) Come on, how many things can actually make you ROTFL? Poor yellow fellow has lost its meaning.
