the moment when a girl raises her butt off the bed and her pelvis into the air, allowing you to proceed with undressing her, rendering her completely naked.
It’s kicking the winning field goal; it’s Christmas morning; it’s the Sun.
Then you go for it. You grab tight and pull with confidence. Your toes are crossed. You’re upon the moment, you hope.
HER BUTT LIFTS! Her butt is UP! You got it!! You got the BUTT LIFT!!
