A writer without a crew. Now it's just a way of saying you are the first one with that name. Almost everyone puts "one" or "oner" after their name, hence the meaning of it is slowly losing importance in the graffiti world.
Among oner don't rep a crue.

Among one is the first one writing among.

A pedant writes:

This is a mis-spelling of the more correct onanism.

Onan is a person described in the Bible (book of Genesis). He was the second son of Judah. His name is the origin for the sexual term onanism (synonym of masturbation), which many consider to be based on a misinterpretation as it more properly refers to spilling seed...

After his older brother Er died Onan was to marry Er's widow Tamar. According to the Bible, when he had sexual intercourse with his brother's wife he spilt his seed upon the ground (Genesis 38:7-9); the Bible says that he did this because (under the custom of levirate marriage) the child would not be considered his, but his late brother's. In response to this transgression, God killed Onan.
'Onerism, you ill educated peasant, surely you mean Onanism!'

Instead of 'Oh Fuck' one would use the following 'By Onan's withered Balls!'

Well, you could if you wanted ;-)

when you don't want to be part of any formal office parties you say "it seems ONEROUS." Nobody will understand it, but they will accept it.
Are you going to participate in the gift exchange? No...I thought about it, but it seems too ONEROUS.

Tossers! Shouldn't they be practising onerism in the privacy of their own rooms?

Four giants that are members of a Chinese boy group under Qin's Entertainment that debuted on August 30, 2018 with their album "Allergy".

All four members was known to have participated in the Chinese idol survival show "Idol Producer".

Members:
Yue Yue/Pinkray (Yue Minghui) - 183cm. The rapper, leader and the oldest of the group. Otherwise known as "the nation's baba (daddy)" and mom of the group. He graduated with a Engineering degree from University of Glasgow and is fluent in english. Probably the most sane one in the group.

Mu Ziyang/Kwin (Li Zhenyang) - 188cm. 2nd eldest and 2nd tallest in the group. 100% sure he's always on crack. Hates & fears crabs, but loves beef and wine. Someone please teach him proper english. His voice is STUNNING. He graduated from Beijing Institute of Fashion & Technology as a professional model.

Bufan/Katto (Bu Fanfan) - 192cm giant. 2nd youngest & the tallest one in the group. Also the rapper. Looks like he could murder you but is actually a cinnamon roll. He also graduated from Beijing Institute of Fashion & Technology as a professional model. Soft tol husky-like giant who needs love and attention.

Lingchao/Didi (Li Yingchao) - 182cm baby. Is the youngest ('01 liner) and looks like a cinnamon roll with the voice of an angel, but is actually satan's spawn. He uses his cuteness to get his way. Eats too much candies. Probably needs to go to the dentist. "Didi on top". Mama fans will eat you alive if you try to hurt or sexualize him.
Person 1: The greatest boy group!!
Person 2: Oh, you mean Oner?
