a wingman is an amazing bodyguard/ brother that PUA's or DJ's have
, as an example.
they 1. help you fight off girls that you wouldn't like to dance with (ugly girls) lol
they 2. discuss with you back and forth how to handle a situation you may come upon at any given moment.
they 3. help with any AMOG's bothering a group of girls.. an AMOG is of course a alpha male of the group. (Personal experience i had a AMOG incident this guy acted like he was the toughest guy on the block.. he was 5'2 i'm 6'2 not a nerd lol i could kick his ass,but why result to violence, i was in a group of girls i just walked up to with my wingman, me and him made a couple of jokes at him and kept our cool and he actually left and we kept the girls (they even said after he left that he was an ass) but wingman help with tough situations you may come upon and support you with insights you may not know. and side note the girls came there (4 of them) and the AMOG was trying to get with one of them but she was denying him. until me and my wingman came along.
and finally lol they are like a brother, an extra hand if you ever had a situation that the girls were sisters and one wouldn't leave the other... lol ya happened to me i had a wingman with me and we were able to take the girls home with us and we just ended the night well.
OH! and wingman help with one-itis as said before and any denies that girls may give you a wingmans always there to cheer ya up lol. you just have tp find the right one
