Rice Gum's brags about his genital length but it actually 5.3cms long. Its small dick energy corrupts all it touches. So only tissues, his hands and his friends biscuits.

Two definitions:

- someone who shows off masculinity by being cocky, showing off, overly confident to overcompensate their 4.2 inch fully erect dick.

- rounding your dick size 2-4 inches up.
Example 1: "Liam has a lifted truck, wears tapout, works out and acts HARD (douchebag) to overcompensate the fact he has a micropenis and can only please a girl in bed with his tongue"

Example 2: telling a girl that you have a 6 inch penis when in reality you have a 4.2 inch dick.

Small dick energy right there.
