The 'I've Seen Some Shit' meme typically features an animal or person with an intensely wide-eyed, haunted expression, often accompanied by a thousand-yard stare. It rose to prominence through various viral images, most notably Stains the Dog from a television appearance and the Vietnam Flashback Dog edited with archival war imagery. The meme is used to humorously represent someone who has witnessed something traumatic, bizarre, or morally questionable. It serves as a perfect reaction image for internet users who have stumbled upon disturbing threads or experienced particularly stressful life events that leave them mentally scarred or forever changed by what they have witnessed.
