hot tub effect

when you drink alcohol while sitting a hot tub; your blood pressure is low when you are sitting there, so when you get out and it picks up, the sudden rush of alcohol through your veins hits you like a train

Davison: I had the hot tub effect like a mofo last night.
Cooper: Vodka and Gatorade again?
Davison: Yep. I got out, and it hit me like a train. I stumbled all the way back to our place.
