The sort of game you play with the provider whenever you go into a massage parlor to see if they are willing to give you that special "happy ending" (i.e. a handjob). You 'lay your bet' (make the first move with some sort of signal), and then they either 'call' (wait for you to make another signal they can trust because they're afraid you might be a cop), 'raise' (lead you on but give no sure indication they are willing - meaning they're cautious but don't want you to lose interest), 'fold' (give you that boner-shrinking NO), or 'go all in' (meaning she's willing to give you that handy, and maybe even let you go 'all in' her!). And unfortunately, just like poker as well, she could be bluffing - leading you on for whatever reason but, when it's time for that final bet, she folds.

A phrase to describe someone who is cognitively degenerating. Synonym of "going off the deep end". Can have varying degrees of severity.

Reference to the song "Hey You" by Pink Floyd. The line "and the worms ate into his brain" makes no sense in an otherwise linear and literal narration throughout the lyrics.
