Insane is one of the many traits that your Sim can have in the Sims Social. According to the in-game description:
"Insane Sims may be silly, dangerous or downright bonkers but they're never, ever dull."

Having the full 4 levels of the Insane trait can restore your Sim's Social, Hunger, and Fun needs at no Energy cost, making it almost unnecessary to talk to neighbors to become inspired. Arguably, this is one of the more useful traits because it saves (your energy) and ((time used during trips to visit neighbors) or (time used inviting neighbors over)).

Note that clicking your Sim's social button at other people's houses can cause your Sim to talk to itself instead of interacting with the other Sim.
