You know how some guys go with the , all I see is red bruh and I ' m unstoppable ? It ' s kinda like that . Unless they have rolled before , they really have no perception on how vulnurable they are in general . 100 pounds means nothing if you don ' t have the software to use it correctly . Sizetraining matters . It ' s not like Bjj suddenly makes you a killer . But it does make you that much harder to deal with . Theres always going to someone who can fuck you up . and it takes time to get good too . Washout rate for Bjj is stupid high as is but I ' m sure a blue belt girl would trash any inexperienced guy within 50 pounds . <| sep |> We had a really big snowfall one year and my son and his friends , unbeknownst to me , decided to jump off of the second floor balcony into it . The first I realized what was going on was when I saw something very much like this through the downstairs window .
