i was out for a work's do, we were in a club, a friend arrived late and me and anotehr friend went to meet her at the bar. there was a man standing right close behind her as if he was with her and when he saw me and friend 1 trying to get her attention, he moved back slightly and made a gap between her and him and put his arm out as if to guide us in. i assumed he was her boyfriend. when i moved towards friend 2 the man put his hand around my waist, i stepped backa nd gave him a funny look and asked friend 2 if she was with him. she said no, she didn't know who he was. i moved away and he moved round behind me. i warned him not to touch me and straight away he moved up against me, i moved again and said "don't touch me". he moved away and my friends and i stood talking. literally seconds later he moved up behind friend 1 and started rubbing her arm. she linched and gave him a dirty look, he seemed to think this was encouragement and put his arm around her waist, low down. she moved againa nd he made to follow her and i said "she doesn't want you touching her, go away". he stood back a bit and we started talking again. he moved to the otehr side of me and started pressing up against me and trying to touch my bum, i moved again and said "I'm warning you, don't touch me again", again he seemed to take this as encouragement and went straight to touch me again and i screamed at him really loud "don't fucking touch me, you fucking pervert." people started looking and he put his hands up as if to say "i didn't do anything" so i said " you were standing there trying to grope us. we don't want you touching us. fuck off" still everyone was looking. he didn't move away but we did and he FOLLOWED us and tried it again. i screamed again "i am fucking warning you". we quickly left the whole bar area. i am furious. he was clearly drunk but he was smirking the whole time. i drove tonight so this wasn't an alcohol fuelled reaction. one of the people i was with seemed to think i was hilarious.
