I.S.S need help!!!

Ok Friday at school aka yesterday I kinda had a huge problem... In science class Ralph,Bray,Dezarea,Alison,and Jacob were sitting at my table and Dezarea was all like screaming show it to Nikki show it to Nikki! And Ralph said ok Nikki stick out your hand so I stuck out my hand and he drew a star in my hand and said close your hand so I closed it he said ope n it so I opened it and then he said you gotta slap a boys butt now. & im like OMG and later I did that to dominick and so later in pe jaslyn one of my friends had had that happen to her and so she slapped jacob {her crush} butt and then she's like omg thats fun I wanna see how many boys I can get and so I laughed then my bff dominick aka MY bf was talking to me and so I slapped his butt and then jaslyn slapped jonathans and matthew l. heard about it and him nick and jonathan were over there trying to slap erica and jaslyns butts and I went over there and tried to help then and then matthew slapped my butt and jonathan tried to and I slapped matthews and we were all chasing eachother around and doing that and then the teacher said to stop but we kept going and then our science teacher said she saw jaslyn nearly holding him down and spanking his butt so she called our coach and then Izaiah and felipe got into a fight over who's turn it was to throw the football and Izaiah tried to punch felipe and felipe tried to punch him and isaac aand someother boy was trying to keep them from killing eachother and matthew was over there yelling fight fight fight and the teachers blamed that on us too. And now im either gonna get expelled,I.S.S or coach said some crap about that happened last year and that kid got probation erica didn't get in trouble ralph didn't bray didn't and izaiah didn't even though they were in it and now im kinda scared and my bf hates me because of that stupid game and my worst enemies are all like you should get I.S.S you deserve it!!!
