The 'Dat Tho' (a slang variation of 'That [Something] Though') meme emerged as a shorthand for expressing intense admiration or fixation on a specific detail of a photo or situation. Usually accompanied by a character making a 'lustful' or highly impressed facial expression—most famously a man biting his lip or an edited image of Ash Ketchum—the phrase highlights a singular, standout feature. It gained massive traction on platforms like Tumblr and Reddit in the early 2010s. Today, it serves as a versatile reaction template for anything from impressive gaming graphics to appetizing food or stylish fashion choices.
