- "Bring out the Beast."
Horn Deodorant is a deodorant brand in Grand Theft Auto IV. Horn is a parody of Axe men's deodorant and the effect is that it lasts 48 hours. Horn billboards and advertisements can be found in some areas; the most notable one is located in Star Junction because this billboard features a large elaborate tube which looks like an enlarged horn. At 1 pm, large amounts of green gas are sprayed out of the end of this horn, to simulate the deodorant spray. It stops at 2 pm.
