A tuit is a token; with enough tuits some task on a TODO list can be gotten to. This is a pun on "get around to it" which might also be read or more likely heard as "get a round tuit" whereby having an imaginary token, or set of tokens, is required before work can begin. Presumably working reduces your tuit store, and rest recovers it. Not having enough tuits generally means there is insufficient motivation for the task or that you are busy with something else.

The above notion is not without precedent; a real token might be used if there is some shared resource (say, a backup device) and only the person with the token has rights to use the resource. The real token could evolve into a virtual "baton" to indicate who the lead is for some task or the other.
