abstain

Seriously.  Just mayonnaise.  Different than those stains all over Kent's house.

     abstain (v.)  to hold back or refrain

for your edification:  By now you should know our methods can get dirty.   So, if you get offended, well, it’s kind of on you, now, too, for continuing to read these.  Anyways.  Let’s break down abstain, okay?  Abstain is comprised of “ab” and “stain."  Let’s agree we should go ahead and refrain from letting any strange stain appear on our abs.  Do you catch my drift?  Let’s seriously hold back from any (ahem) activities that would lead to any stains (!) that might shoot out and land on our abs.  (Dude.  Remember when I told you about that guy Kent whose house is called "Spankquarters" cause he couldn't abate the 'bate?  His abs could be called "Spankquarters", too, on account of all the ab stains all over his abs.  He should really abstain, just to help his mom save on the family's dry-cleaning bill!

Our example today is a riddle.  Everyone loves a riddle!

examplification -  Crystal:  Why does Skinny Jim have a big mayonnaise spot on his stomach? 

Billy:  Skinny Jim couldn’t abstain from the ‘bate again; because he didn’t abstain, he now has a big old ab stain. 

Carl:  It’s jiz, dude.  Not mayo.  Next time he should just abstain.
