Car does say those ever once in a while. 
A lot of people use that crying laughing face. 

I used to have a friend who always said 'le-mao' when something funny happened, and I didn’t understand for a long time that he was actually saying 'lmao.' I always thought he just liked the sound, which sounded a lot like a cat’s meow, but with a French article in front. I just went along with it.

I thought his lmaos are like @Car‘s woo doggies!

lmao.

I've noticed that jajajaja is commonly used, mostly in the Thai community, similar to how they use 555555. Additionally we can include Bahahahahaha and XDDDDD as well.
