[SPOILERS] Pop culture references in dance animations?

[minaboo]

Please do not read any further if you haven't finished what is unlocked with the Key of Old Habits.
This post contains spoilers!

So, I entered the Room of Old Habits above the casino entrance with the full set of cards in my pocket and reached this scene where everyone is dancing happily. And I noticed that some of the dances danced by the guests there looked familiar. For example:

• Tequila and Aurum do the 'Single Ladies' choreography by Beyonce
  
• Grayson and Redd dance the 'Crank that (Soulja Boy)' dance
  
• I'm not sure about this one, but I think Trinity and her husband (forgot the name) are doing that dance scene from Pulp Fiction

And now I'm curious if the other guests might be doing as well movements which could be seen as pop cultural references. Actually, it drives me crazy not to know what Willow and Reginald are dancing there.
And maybe there is some reference hidden in the slow dancing of Lucas and Eleanor as well?

Please help me figure this one out! (And sorry for the bad english, I'm not a native speaker)
