what has your experience been with shrimps spoiling?
I tend to pre-empt these people generally. I rarely notice shrimp types really interrupting except through accident, usually they tend to stay clear.
EXCEPT shrimps who you have befriended, they can get needy and they can spoil your interaction without even really wanting to , they just get needy and start to hover or talk to you or whatever. I lost a one itis like this a decade ago, a girl I really liked. I could still get her but it became very foggy and fucked up so I got another girlfriend instead. But I remember that I promised myself there, when a friend comes in.. just tell them to fuck off real fast. You can make amendments later. This has saved me a lot of girls!!
Amogs I deal with in fast hostile way when I see them coming in, usually one sharp look tends to suffice, I tend to notice them coming in. They get these weird needy eyes. Basically I show preparation to escalate if they intrude, I have no patience for these suckers.
Another thing that needs to be dealt with, something I encounter more than before, women who are jealous of your target and are targeting your girl in an effort to derail your conversation. I find these girls more difficult to deal with except jarring them and interrupting again "hey we were having a conversation" and body close circle, but I am still not sure if this is the optimal way as the girl who you are talking with is sometimes not tuned in and not even aware that the girl is not coming in friendly but sabotaging her effectively. Sabotaging my target more than sabotaging me.
I recall one girl fucking up an interaction I was having and being overly persistent and I naively thinking that the girl I was with was suave enough (she was older than 30) to deal with the younger girl. I was not really gaming the 30 year old either, but thing is she didnt even see it coming that the intruder came to sabotage, and do you think she ever went to talk with the 30 plus girl again? Nope. The goal was sabotage.
