When you act like a simp to a friend to be sure that friend will be loyal to you and trust you. The more you friend-simp, the more that friend will trust you. It's used more when you are not used to have many friends or actually don't have any, or when you want to make that friendship to last more, in the first case you won't be able to stop friend-simp because you mostly will feel scared to lose your friendship, not even for a minute.
Friend-Simp (friend-simping): "Hey, (thinking about how he did well on the basketball game yesterday) hows going with your girl? Everything alright?"
