Meth Breath and Meth Man

There is this married couple that goes to the gym that I affectionately call Meth Breath and Meth Man. They are the friggin' greatest!
After a couple of years of watching Intervention and Celebrity Rehab, I have diagnosed them as Meth addicts. The woman, a pale redhead that may not be that much older than me, wears this teeny tiny hot pink bikini that is right out of an 80s music video. But she doesn't shave well enough, so when her bikini bottom gets wet and heavy, it sags down her jay-jay and you can see her fire-red pubes! That's a token sign of a Meth addict- just not giving a crap. But even the bad swimwear and hairy bikini line I could forgive if her teeth didn't look like she has been chewing on sharp bark (another Meth symptom). This the one trait she shares with her odd-ball hubby.
At first glance, you would think he is her father. He is old enough to be. But their body language toward each other, which is so hot and sexual that you fear that they will stop and do each other between pool laps, makes it very clear that they are together. Don't get me wrong, they are both socially awkward, but her husband is so on edge with his beady brown eyes that you just sense that at any moment he is going to pop out of the water and yell, "I'm on drugs OK!" He is also QUITE hairy. The whole back of him looks likes a rug, and to see him wet in the pool would make you want to hurl. How can I explain him? His young bride and his crazy facial expressions lead one to think he has done something really, really bad making you convinced upon first glance that he has molested a child or something.
One thing is true though: they are clearly in a beautiful, codependent love. I guess there is no love like Meth love.
