FU can act as an adjective describing units in RTS games. It stands for Fully Upgraded. Mostly seen in forums, rather than in games.
person1: Of course British Lifeguard Hussars beat French Hussars, they are royal guard units ffs.
person2: Not when fully upgraded noob. The French can increase their hand cavalry attack by 15%. That boost means that FU French hussars beat FU British hussars.
