Have you ever had to cut off a loser friend?

As condescending as this question seems, let me explain.

So I recently ran into this old middle school friend I knew back in middle school who used to be in breakdancing with me. This was in 2008-2010, so we're both 25 now.

We were thrilled to see each other again and began hanging out. However, I began to notice he was kind of a loser and stuck in an immature high school phase. 

When we first started hanging out, he would talk about all of the drugs he liked to take and actually filmed himself doing them. He would make me watch for over an hr. He would also brag about all the women he's slept with which is something I never admired even in high school. On top of that, he would also talk about himself and his achievements ( sex, drugs, video games, etc.) for hrs, and he wouldn't let me talk about myself for even 5 minutes. 

One day while we were hanging out he decided to take me on a tour through Rice University. Apparently he had three girlfriends there, and he would show me all the areas where he either made out with a girl or slept with one. The kind of thing you would see in an "American Pie film".

The final straw for me was when he invited me over to his house to tell me his future goals. He wants to create a podcast, move to Japan, and live off of the money he makes from the podcast. He has a huge fetish for japanese women, so he plans on pumping and dumping over there. 

Honestly, as a 25 yr old, I feel like i'm too old for friends like this. Your thoughts?
