The image appears to be a meme that is meant to invoke humor through an exaggerated scenario involving jealousy in a relationship. The text at the top of the image states, "When your bf comments that another girl's selfie is 'hot af'." This is a common expression indicating that one finds something very attractive, and the use of the abbreviation "af" stands for "as f***", which serves to emphasize the level of attractiveness.
In the foreground of the picture is what appears to be a representation of a Barbie doll with a surprised and somewhat sardonic smile. Barbie is often associated with an idealized standard of beauty and femininity, which contrasts with the context of jealously implied by the meme.
The background of the image features a car that is on fire, surrounded by flames which are commonly associated visually with the concept of something being "hot". Thus, it visually reinforces the text's play on words between literal and figurative "hotness."
Beneath the doll, a caption reads, "Oh my, look what else is hot af babe." This is the punchline of the meme, suggesting that the speaker, presumably the person replying to the boyfriend's comment on attractiveness, is pointedly drawing attention to something else that is literally "hot" - a flaming car - as a sarcastic retort to the boyfriend's comment.
The humor in this image arises from the subversion of expectations, wherein one might expect a jealous or angry response to a partner's perceived (("When your bf comments that another girl's selfie is "hot af""))
(("Oh my, look what else is hot af babe"))
