Every time I give my friend daps, he'll end it with grabbing my index finger with his own and squeeze it two times, kind of like a gun. What does this mean? My friend apparently used to be some sort of errand boy for some shady guys, I didn't really believe it and I've been talking a lot of shit about him with other people, most of the time I think he has told all lies and make it seem like it's personal, and maybe it was. He's been acting shifty lately too, like he'll speak to me with truth and lies about something, I think he's a total liar, and I think he knows that that's what I think, and for some reason is really pissed off at me? I'm not sure what to think, but now I think he's a gang member. He has a scar between his index finger and thumb, I asked him once and it was a long time ago, he said he doesn't even know. He's only 20 years old.
