When you pull the scrotum, with
two hands, further then the end of the penis, making it look like penis (
Alladin) is sitting on top of the scrotum (the magic carpet).
Running around, making
whooshing sounds or screaming "Jasmine! Wanna go for a ride!?" while doing it is recommended but certainly not a must.
Jafir: Hey
Jenny, would you like to ride Aladdin's magic carpet?
Jenny: Yeah... sure.
Jafir: Do you trust me?
Jenny: What? ...
I guess so.
Jafir: *drops pants*
