open faced roast beef 

Oversized, over-used, stretched out vagina lips, hanging from the crotch area, resting on the inner thigh, as if to be an open faced roast beef sandwich.

When your at a party, you meet a chick, you stick your hands down her pants, and there's more meat in your hands than in hers. That's open faced roast beef.

Open Beta 

open beta is one of the phases for modern software development. it is the time when a company either gives or charges early access to a mostly developed or fully developed software title. In return for this early access the end user is requested to report any issues found in the software. The most open, open beta I have seen was window 10. when it was free to upgrade that was an open beta for Microsoft to use people for automatic bug reporting via intelligent software that watches and reports problems in Microsoft to Microsoft.

Hey guys have you played Star citizen yet, its in open beta right now. Ya it was a little buggy, but it was soooo much fun!
