This term is used to describe when one is having unlubricated
sexual intercourse with their grandmother, but the hard penis is too sturdy for the grandmother’s saggy and dry vagina to handle, thus ripping the walls off of the vagina like
paper and the blood pools and fills up the vagina, imitating the
water in the Panama Canal.
Person #1: Hey
bud, how was your grandmother
yesterday?
Person #2: Not too
good, I created a Grandama Canal and she had to go the the gynecologist.
