a good spend
A buy so good, your brain says 'yes' and your wallet says 'no' but you don't care.
That video game? A good spend. My brain said yes, my wallet said no, and I still bought it.
That burger? A good spend. My brain said yes, my wallet said no, and I'm now a human meatball.
That new phone case? A good spend. My brain said yes, my wallet said no, and now my phone is fancy.
