Short for "January tan" which can mean either a winter wind burn/frostbite from extreme cold or a actual subtle tan from an abnormally warm and sunny winter day in January.

Get the Tan Upmug. He joined us in STD5 and he is a really nice dude. But mf is just too nice and wouldn't even let a girl go just forget bro. A HJ is always good at playing drums and has nice taste of music and mf is just so cute wanna squish his cheeks him. He makes all the boys a bit fruity and is everyone's go to uncle. Tan Hong Jun plays volleyball but is very skilled at playing all types of balls as well <3. This guy has so many assets I wrote an essay in BM for him and it is *essential* for everyone to have a Tan Hong Jun in their lives.
Girl 1: OMG look at this cute drawing Tan Hong Jun drew for me
Girl 2: O M G that is so pretty. He's like the cool uncle of the school.
Girl 1: Ikr he's hot as well. He's going to volleyball is this Sunday and all the boys are joining as well
Girl 2: OMG lets join I wanna see HJ Hit balls. :3
