Be Smart And Look It Up People

I was doing a reread on the latest book and noticed I used a word that my Grammar and Spell Check didn't like.  Now it looked like a perfectly good word to me so I fell back on the old but tried method I use when I have any doubt.
I look it up on the internet.  Sure enough the word was there along with the definition.  I'm good.  I read the definition.  I'm not so good.  Actually I'm not good at all.
So what was the word?  Tosser.  Yes tosser.  Now I'm not going to give you the definition because if you want to know then you are going to have to do what I did and go look it up for yourself.  Yes we've established I'm mean so move on.
Anyone who has read any of my books knows that Alison, one of the characters in my books, calls Emma, another character in my books, silly little pet names regarding what she does professionally.  She's an Archaeologist.
Alison calls Emma cute little names like Crypt Crawler, Sand Shifter, Mummy Mugger, all kinds of stupid little titles.  Well the word tosser was used in one of those names, i.e. Tomb Tosser.  That's right.  Now some of you will get this but my bet is there are quite a few of you who want.  For those of you who do get it you can stop laughing at any time now and for those of you who don't you will after you look it up.
I have to always put two words together for these titles with the same letter beginning each one.  The kicker is that there is a word I could put in front of the one word meaning of tosser and still be following that rule.  No I'm not going to tell you what that word is but if you find out what tosser means and want to figure out what word I could have put in front of it is  to make it work please feel free to send a comment.  I really would like to know how many people who can figure it out.  Here is a little hint for you guys.  The word I could put with the other word for tosser is also another word for tomb.  Now let's see who can come up with the new two word title and is willing to get back to me. No I am not about to use it in the book.
