Coined by Alinator, a part of the Dark Triad of simping (Desperate Simp, Financial Simp, & Sneak Simp) a sneak simp is the act of simping or being a simp very secretively, especially acting like you are not a simp around your friends & others, then behind their backs you simp hard. This is worse than being a financial simp & an openly desperate simp because it is shady, and extremely untrustworthy. If anyone of your friends find out that you sneak simped, don’t blame them for dropping you, no one likes a shady ass simp ass nigga.
Did you hear that nigga went behind our backs and simped for a bitch while telling us to our faces that he didn’t fw her care about her and he ignored her all the while he was doing all that shit making us believe he was based yeah fuck that nigga can’t trust no sneak simp
