A "munch" is a slang term that originates from Bronx drill rapper Ice Spice and her song "Munch (Feelin U)". It is a term used to describe a person who is obsessed with someone else and often expresses it by wanting to give them oral sex. In other words, a "munch" is a sexual partner who solely performs oral sex and doesn’t penetrate. The term is similar to the word "simp," as in a man who is only good for giving oral sex on a woman due to his blind obsession with said woman. The term has become popular on social media platforms like TikTok and Twitter, and has been used in memes and viral videos.
