Terrible Terrible Smell, Soooo horrid. He is my used-to-be-friend?

He always wanted me to come over and I did once, it smelled like... I don't know! it's just terrible. his whole house smells like he does and he says he showers. I could believe that he does because I think it's just his house. It just smells soooo bad and i can't figure out what it is. I would say it smells like cat pee but you guys would think it's meth, but it's not, he's checked haha everywhere. And it lingers as well, for about an hour. He's came over and gaaaa it's just soooooo badddddddddddd, you guys have no idea. It doesn't smell like poo, it doesn't smell like body odor. He does have a dog. hmmmm but the dog smells fine! It's just like you are engulfed in the smell when you walk in, it is soooo ooooo ooooo ooooo ooooo oooo bad.
