Lore
Vibe Check Engineer made his first appearance on r/okaybuddyfortress on September 30th, 2019 through a post by u/MrDownwardspiral. The post depicted the Vibe Check Engineer looming over the character Ashley, who is apparently unaware that she is about to receive a vibe check. The post was titled "OMG GUYZ ENGINEER IS GONNA GIVE ASHLEY VIBE CHECK OH GOD OH FUC". However, this is not the first instance of a Team Fortress 2 character, or even the Engineer, performing vibe checks. Vibe Check Engineer did appear nine days prior in a two panel meme on Tumblr depicting the Vibe Check Engineer performing a vibe check on a Blue Spy, exclaiming "Yer vibes are lookin' pretty damn rancid! No prior instances of Vibe Check Engineer seem to exist, and of the three existing images two are r/okaybuddyfortress material, so it's basically u/MrDownwardspiral's meme.
