2.
Someone who is particularly smelly, and consists of a lot of unwanted personality traits. Someone who is a gym-bag is very irritating, and gets on everyone's last nerve.

A gymbag is someone who brags excessively about their workout regimen.
I went on a date with this guy last night, but all he did was talk about weight lifting, spin class, and how many times a week he runs. What a gymbag.
