A complete fucking monster dick

When you can't decide between complete dick and complete monster.. Can refer to a partner who swindles you out of 30k and then breaks up with you to hookup with someone asap

Me: "I just got bamboozled. I thought it was the real deal, but I just lost everything.. :("

Friend: "damn. You just waisted a year and a half on a complete fucking monster dick."

P.S. both of those are actually just me, I'm just really sad..
