Do you mean the LE check when you first meet?  Some ladies do the squeeze test, they grab your junk, you grab their breasts...LE would never do that!

The urban dictionary is a great resource for newbs. You won't have to post on this board and then wait, you will get your answers for slang and acronyms right away.  You can also do a search of the board. It's back on the first page up top. This question about le check was just asked a few days ago.

I once got asked, "are you a cop?" I simply assured her no, but I really wanted to be ask her why she bothers asking. Would she expect a cop to say, "oops, ya got me. I never thought you'd be smart enough to ask! Damn, another sting down the drain."

Seriously, it doesn't exist.  Don't get lulled into some sense of false security by this.

LE can do anything including lie to you about being LE.

Stick with well reviewed gals and forget all about so-called LE checks.
