There are these two girls that stay across the street from me should i whip their a** or no?

Once they played on my phone and left a message that said they wanted to get all up in me and my friend.and that piss me off alot.and when i seen them after that i woul always say something to them and the wouldnt say anything back or look my way.now a girl i used to hang out with is with them and i think she is telling them things about me and my friend and i want to whip her a** cause she act like she hard on the phone but when you see her and her friends they wont look at me at all.but now her friends cousin is over thier and this b**** dont even know me she been over here for 3 days and every day she stare at me but one say anything so yesterday her and my boyfriend had an argument and when he left they was coming from the store and her cousin was like all i know is she better control her man. thats when i said b**** you still talking and she got quiet and they never came out again i know their scary.should me my friends that dont like them shut they a** up or what
