testing the waters

-- when you have no idea if something works, and you go at it tentatively
-- metaphorically like sticking your finger in coffee or tea to see if too hot

was just testing the waters, wasn't really serious

NFL2G

-- acronym ( initialism ) for No Fucks Left To Give
-- when you are totally out of fucks and have none left to give
-- either none left for the person or purpose of the moment
-- or none left at all, which is more of an existential condition
-- especially useful for twitter, texting, and terse emails

-- i am totally done with this, this is your problem, don't bring this up again
-- dude, you can't go NFL2G on me when I've saved your ass so many times
