slug monster 

i) a general analogy for all things terrible and horrendous in nature.

1) ripping someones shit out by sticking your arm elbow deep in their face is a type of "slug monstering".

2) If a child is vampiric then by law you must axe their throats. This is another manner of slug monstering someone. Or SM'ing their shit.

Slutmonster 

This chick is an all-out flithy skank. One could definitely score a rim job off this little number. Good for a quick game of hide the salami as long as you double wrap it.

Horn: "Oh man, that chick looks like she would totally let me donkey punch her... what a slutmonster!"
