Work Made Us Coworkers, But Our Potty Mouths and Inappropriate Conversations Made Us Friends Co-worker Humour Wine Tumbler – Let’s be real: the only thing stronger than a work bond is a work bond laced with bad jokes, office banter, and questionable conversations. This wine tumbler celebrates the friendship that was really built in the trenches of awkward meetings and accidental swear words. Perfect for the coworker who’s made your workdays a lot more bearable—and way more fun. Cheers to surviving work stress with style, sass, and a lot of laughs!
