The post you are reporting:
The term 'to level-up', according to the WGS Dictionary of Historical and Contemporary Cant, means:
'to present large-scale, fully taxpayer- (or magic money tree-) funded, hyper-real, utopian PR exercises designed to lead the gullible into believing that the reality they live in isn't the crumbling liberal dystopia they think it is, and to provide "enhancement opportunities" for the various politicians, councillors, lobbyists, designers, building contractors, accountants, marketing executives and special interest groups involved'.
Admittedly, this is from the 2023 edition, so some things may have changed.
