"Thirsty pics" typically refers to a suprising and slightly crude representation of pictures (often selfies or images) with the intention of appearing attractive or seductive, usually in a somewhat exaggerated or overt way. The term "thirsty" in this context is slang for being overly eager or desperate for attention, especially of a romantic or sexual nature. The transparency of the attempt of attention-seeking or provocative nature of such attire, while also embracing it as a form of empowerment and personal style, makes the visual more appealing to the viewer.
The meme might also highlight the fun and flamboyant aspects of gay culture, using humor and vibrant visuals to convey a message of confidence, acceptance, and the joy of being unapologetically oneself.
Oh Fuck another Facebook ad… I’m gonna send these thirsty pics to my friend.
