The phrase "gat someone the horn" is a slang term in British English that is used to describe when someone is sexually aroused. The spelling of the word "gat" is a variation of the standard English word "got" and is pronounced /ɡæt/. The word "horn" is pronounced /hɔːn/ and refers to the male sexual organ. While this phrase may be commonly used in certain regions, it is important to be mindful of the language we use and its impact on others.
