Someone who can't control their flexing and doesn't even kow when they are doing. They think they are jacked and always do it to impress girls. Also, Sir Flexalots flex 24/7 a day and gained their muscles theough no workouts. Finally, they feel that their are weight more than their actual wight.
Connor , stop flexing at me, you're such a Sir Flexalot.
