To be lazy. While a poot and pooter are very different things they all derive from being somewhat shitty. If your sitting around being lame instead of going out and having fun, your being a poot or partaking in the act of "pootering."
Stop pootering around and get off the couch!
Pootering is the use of a laptop, or similar computing devices, while on the toilet.
Yeah, I took care of those emails while I was pootering on the shitter.
