A simp is a someone who would do whatever to get a girls attention. But the term is now used when a guy is being respectful to girls. So if you're a simp, be proud of it.
Guy 1:slaps girls butt* "ey fat ass"
Guy 2: "don't touch her dude"
Guy1, guy 3 and guy 4: "SIMP!!"
a person who has no sense neither of self respect, nor of brotherhood among friends.
that person would not hesitate to do ANYTHING and stoop down to any level just to impress his/her "crush"
