Spending like the bill is someone else's problem, forever.

means Reckless, wasteful extravagance — in money or morals — with no apparent limit or restraint.

from Rooted in Latin profligare, 'to strike down, cast away, ruin' — from pro- ('forward') plus fligere ('to strike,' the same root giving us 'afflict' and 'conflict'). A profligate person was originally one who'd been struck down or dashed to ruin; by the 1700s the word had drifted from describing the wreckage to describing the reckless living that causes it.
