a Textovel is sending a very long text message that usually will be broken up into seperate messages because u went over the character limit, resulting in the reciever to look through 3-5 pages of text from you
Guy: hey whats up?
Girl:nothing much hbu? omg today me and lucie where at the mall and there was this one guy...
after reading her textovel the guy became very aggitated because he doesnt have unlimited text and each new message in his inbox costs him money
