Deja-Who 

When you see someone and you know you've seen them before. You insist you've met and they deny having ever seen you.

Guy: "Hey, where do I know you from?"
Stranger: "I don't think we've met."
Guy: "I definetly know you from somewhere."
Stranger: "Nope."
Guy: "Sorry I must be having deja-who."

Deja Who 

A condition where one meets a person over and over but the other person can't seem remember them.

"I met that Michael guy at Mary's house warming last year, at Alice's holiday party last year and I just got re-introduced to him last night at Joan and Bob's. He said 'Nice to meet you' like he's never seen me before. He has a serious case of deja who."

deja who 

1. the unexplainable feeling you have never been
here before

2. the knowledge this place/time has never existed before
and is not likely to ever exist again

3. metaphorically called
"the Calling of a Time Lord"
please do not confuse with "deja who" ≈ deja vu as experienced by Doctor Who

When the Deja Who hit the Time Lord, she knew she had to end that time wobble.

De ja whoomp

The overwhelming need to dance brought on by hearing the 'whoomp whoomp' sound in a drum n' bass song that you previously heard when you were on MDMA.

Similar to a de ja high, but more of a bodyfuck than a headfuck.

*Dancing around a living room alone to Sub Focus*

"What the fuck are you doing?"

"Oh dude I just heard Special Place and it gave me such a de ja whoomp."
