Txtspeak

From Frikipedia

Hideously annoying manner of writing, developed solely because mobile phone companies insisted on limiting text message sizes to 160 characters. The greedy pinstriped bastards.

Essentially involves dropping all the vowels from your words, so in essence it is not too dissimilar to Welsh.

True txt speak professionals can instantly turn a simple invite to the pub into an indecipherable waste of the 12p text charge in seconds. They tend to get ignored and people stop inviting them to places.
