monica calls rachel skanky ?

Yeah I hear ya. Sad & messed up that Monica tricked Rachel in being her friend and then turned on her at the party. To answer your question, Monica was just being a bitch when she called her "skanky". Even Mark called her that to Jesse fyi. I am glad though that Rachel made that evil bitch's glasses shatter in her eyes. I cheered & laughed at that scene

Did you know that people tend to judge others more harshly than they judge themselves or those that are close to them? or that many of the words used to describe promiscuous women are nothing but words of anger?
