<human>: About 3 years ago, I made a remark saying, "Suck my 8 inch cock!" My friends called bullshit, and we went on with our lives. Now earlier this year, they brought it up again, saying that I was over-exaggerating. I got really pissed off, and then we blew it off again. This afternoon, at around 4 pm, I read an article that was posted on the front page talking about the average erection sizes. It said 2.5% was 6.9 inches or greater, so I sent that to my friends in a group chat on kik, and they called me out again. I decided enough was enough, and because I was sleep-drunk, I sent a picture of my erect dick to a friend in the group chat through snapchat with a ruler for comparison that lasts 2 seconds. I said check it, and my friend got really worried about it, and still didn't open it. Meanwhile, my other friend calls bullshit on me once again, saying that there is no way that I have an 8 inch FLACCID dick. I was shocked, and asked if he meant erect, and he said no, then he completely believed me. My friend who has the picture won't respond to my messages, but he still hasn't read it.

Can you condense the text into a few key points?
<bot>: I sent a picture of my erect dick to my friends trying to prove that it was 8 inches, when it turned out they thought it was 8 inches flaccid
