When under social pressure to follow the crowd to do something or act a certain way and refusing to do so results in being called a "wimp". When in actuality it being someone of inner strength to resist.
Ah, come on, jump the do not crossfence! We did it! Quit being such a wimp!
A wimp is like simp (Suckers Idolizing Mediocre Pussy), but for women. Women Idolizing Mediocre Penis. When a man talks a big game about his sexual prowess but really he's just another 2 pumpchump.
Girl, don't wimp over that fool. I hooked up with him 3 months ago and he lasted about 5 minutes before he blew his load after bragging how great he is in bed/how long he can last. He's a fucking chump.
