The actions that a Simp takes that make them a Simp in the first place. For example, knowing a girl is way out of your league but then bringing her soup when she is sick thinking you're going to get something in return.
Boy1: Damn bro you're really showing some real Simptoms.
Boy2: Nah man I don't just do anything for any girl man she's gotta mean something to me!
Girl: Hey I am sick please bring soup even though we're neither friends nor romantically connected? :( :( :(
Boy2: Yes my sweet queen my shining diamond, my kitten, my goddess, my muse, my darling I'm not like other guys sweetheart I'll bring you the best soup unlike your ex who didn't care like I do because I am a nice guy!
