A phrase used when experiencing an intenselyawkward situation. (often used in conjunction with a hand gesture: Flat hand, palm down, rising as if to indicate an increasing water level.)
Blub is a nickname to call a loved one such as a girlfriend/boyfriend. It can also be used to address a person/animal that is related to you, cute, chubby, or lethargic.
There are only two true blubs in the world though.
