Apparently texting-speak for "atleast". That is, without any space. If you type in 2853277, because you're too dumb to know 'at least' is two words, the phone apparently suggests 'culdart' to you. This editor uses proper keyboards to communicate, but knows people who actually use this like a real word on myspace and such.
