The meaning is "loser". The word originates from the word "cup" which again gets its meaning from the grade of "U" which signifies a fail grade at IIT Madras. Therefore calling someone a cupper means that the person is a loser.

A one-handed masturbation technique in which the practitioner vigorously stimulates his member while forming a basin or "cup" with his free hand. The stroker then ejaculates into the free hand, thus collecting the product in the aforementioned "cup". This technique allows the "cupper" to admire his work while closely studying temperature and volume. "Cupping" is generally used to ensure an easy clean-up however, some have weaponized the practice by throwing the collected jizz at a high velocity.
FRIEND #1: Dude, why is Jimmy always sniffing his left hand?

FRIEND #2: Leave that cupper alone and let him admire his work.
