OP here...holy heck, I didn't know this would blow up! I'm cool with people not liking it. If I wanted everyone to agree with me I wouldn't have posted on Reddit!

Couple of things people asked:

The party was at my house so obviously I knew everyone there. I did go back and forth about it in case it offended anyone but I got pretty good feedback so I decided to go for it. I would not wear this to a party where I didn't know the crowd.

The gun is a Nerf gun that I spray painted black. The scope is too far forward because it's a cheap piece of plastic and wouldn't go on all the way. Yeah, I should have left more orange on the tip but I didn't think of it. Either way, it's not going out in public.

The clown is my 80 year old mom. She said she was going for a Charlie Chaplin thing, I don't think it worked but she had fun.

I did ham it up. A lot.

Happy Halloween!
