1) Playing around/joking with someone jk but when really you are being completely serious and not so sure how the other person will take it.
2) A way of taking back everything you've just said to someone that you are into, cause you've just realized that they are NOT into you. You now feel like a complete chump/chumpette chump for putting it out there and need a quick way to take it all back and still look cool.
3) A response said to something that has caused that long awkward pause.
