Is there a word for that occasion when you're bored but too lazy to actually do anything about it?

An Estonian phrase “ma ei viitsi" that usually translates as ‘I don’t feel like it" (from the verb viitsima). It is an expression of a mild feeling of laziness and disinclination towards being “bothered” by anything — one doesn’t want to work, go anywhere, or do anything specific.
