lolspeak
Similar to texting, lolspeak is writing words with different letters (but sound the same) than the original spelling. lolspeak can also be misspelling on purpose.
examples of lolspeak:

dunno what happnd, we dint touch it
(Don't know what happened, we didn't touch it)

i can has ice scream?
(I can have ice cream?)

teh itteh bitteh kitteh commiteh
