This is a variation of the acronym TTUL (Talk To You Later). Just with an S at the end. Talk To You Later Sukka.
The S is added mostly for comedy as the TTUL means later, the S is only to add a
brief name
call before the conversation is over. Calling a friend a Sukka is always amusing.
Alternate meaning. Can be used to say Peace out in a psudo-negative way.
