Splurge

To dispense or exude something (generally with a target in mind but not required) in both large quantities and high concentrations done rather quickly, and usually with force, over a very short period of time. Can also be in multiple quick and short successions.

Comes from the Latin word: asplorugem, meaning 'to ejaculate with vivacity'

"I was annoyed since having splurged all my Jobseekers Allowance on cheap prostitutes literally within 48 hours of being paid"

"It might have cost me 2 months' of saved up dole money but she let me splurge down her gutter"
