A good gift for a teenage guy and best friend is a box of his favorite candy. Another good gift is a plaque bearing his favorite sports team.
A newly released video game, CD or movie also makes a good gift for a teenage guy. Gag gifts are always appropriate when purchasing a birthday gift for a friend. This includes giant gummy bears or fake lottery tickets. If the friend is into music, headphones or other equipment is always ideal. When giving a gift to a friend, it is important to show that it comes from the heart and that it is age-appropriate.
