If you see something, say something. Come on and party tonight.

This appears to mash up a public-safety slogan (“If you see something, say something”) with a party-invitation line, suggesting a humorous or satirical intent rather than a standalone aphorism.

It juxtaposes vigilance and celebration to create a comedic contrast, implying that serious messaging can be repurposed or undercut by a sudden shift into carefree partying.
