A versatile word, generally used to describe the following:
1. Master of all things kink related.
2. A total Bad Ass who is extraordinarily well endowed.
3. Super-humanly good in bed.
4. The direct cause of semi-permanent ear damage known as CSE (Cock Sucker Ear). Often associated with the vigorous assault of a female throat by a colossal sized penis during an aggressive act of throat fucking.
Also related to "Swallow it again!!"
When entering the BDSM community, a neophyte should always seek out a MasterOfOMGs for the ultimate experience.
"Girl, His junk was so BIG, I didn't know if I could handle a MasterOfOMGs like that!"
"Gary is a total MasterOfOMGs"
I went to the doctor and they said I have a MasterOfOMGs related case of CSE. Hope it heals one day... Good thing I have another ear!
