Who knew spam could educate you?

I received a spam today with the subject:

pulchritudinous Wild young grand schoolgirls doing aesthetical oldmans

What caught me was the word "pulchritudinous". Is this a real word? I said to myself, so I looked it up. Yes, it is a real word. I'll have to find some way to use it in general conversation with someone to make myself sound ultra-smart.
