I regularly go to social events where it's easy to get in contact with girls. Girls want to meet guys and guys want to meet girls. Everyone knows this who is showing up there. Usually you sit at a table with some more guys depending on the situation and who showed up first. Sometimes when I am already in a conversation with one girl, suddenly one guy (or more) tries to get himself into the conversation, trying to "steal" the girl. You can literally feel they are just waiting for it. How can I deal with this situation and the guy(s)?
