The phrase itself is everyday Spanish for can't you see I'm selling incense, and its appeal as a meme comes from that blunt, street-level directness rather than from a film, song or television scene. No widely documented original source is attached to this short clip, so its identity is the line itself: a seller stating the obvious to someone who should already know. Online it is shared as a compact reaction sound, especially in Spanish-language humour, where the wording alone is enough to signal impatience, sarcasm or disbelief.
