'Doing a Riff' is when one person claims to be madly in love with another person and enjoys telling everyone about it, any time. Then a few days later they have dumped them and are 'so in love' with someone else.
Person1: I love Jen so much! She's so amaaazzzzinnng. I just really, really love her.
***3 days later***
Person2: Hi! How are things between you and Jen?
Person1: Huh? Oh I dumped her. I'm in love with Angelina now. I love her SO much.
Person2: You're doing a Riff again!

Creating a situation so untenable at a club that showing you the door with a fat cheque and no handcuff clauses about your future suddenly becomes the only sensible option.
Pochettino is in a position where he could do a Mourinho but he probably wouldn't want to due to its loyalty to Spurs

Someone who hangs around a rockstar, always riding thier nuts/vag. They are referred to as a do-bot because they will DO just about anything for the star.

When one plays a first person shooter against others and needlessly creeps around corners, crouching or walking, thinking they are being sneaky. Usually followed by either getting shit all over, or pulling some miracle our of his/her's ass and shitting all over the other team.(Must be 3+ survivors on the other team for this to be considered a miracle)
Wow are you really crouching while going through a door? Crouching when YOU know THEY know your there does not make you invisible... Stop Doing the Bill and use some common sense
