A 'Person' typically a male, who becomes obsessively
affectionate, kind or devoted to a certain person who does not
reciprocate the same feeling as what he or she has for them, usually giving unrealistic amount of
compliments, gifts, and special treatments, etc. And does not get anything in return for what he or she has done. Not even a 'Date.
("Note; that the word 'Simp' is a shortened form of the word 'Simpleton' meaning; 'Foolish' or 'Gullible'")
See phrase example below:
He has fallen for a trap of his own! Why wouldn't he stop
being nice to that girl that he has
no chance of getting for, He's such a "Simp" the girl that he romanticizes doesn't even show any signs of
interest on him.
