A-O by hasselhoffman March 6, 2009
A.O is a very fun and outgoing guy. He has a smile that will brighten anyone's day and eye's that alway's have the girl's looking twice. He is a kind, sweet, trustworthy, cute, caring, smart, clingy, loving person that will alway's be there for you. But dont take his kindness and sweetness as a weakness, if you ever dare too touch his girl or anyone in his family, he would be the first guy too beat a fool up.
A.O has alot of female friends, but his girl alway's come before them. If you ever get the chance too be with a A.O, take it and never let him go. Cause if you do youll regret it for the rest of your life.
*Did You See That Guy??....*

*Yeah That Must Be an A.O... Just Look At His Smile.. But Dont Try Anything, Cause He Has A Girl And He Wont Ever Do Anything To Hurt Her....*

*Did You See His Eye's??*
*Yeah I Did.. They Were Green And Sexi*
*Yeah I Thought Soo.. Had Too Look Back Twice Tooo Make Sure.*

Sister: This meeting was to discuss the rough draft of my essay, where we discussed the subsidiary questions I added in my rough draft. We also discussed the relationship between my main title and the real-life situations I chose to use in my essay. We discussed the structure of my essay as well, specifically the Math AOK section and how it relates to the contradiction of the title. This second meeting was particularly helpful in discussing the implications of my essay claims and how to apply the title across various areas of knowledge. There were many sections of the essay that could have been cut down in wordiness and the ways of knowing required further and more in-depth analysis.

Me: Woah! TLDU!

Word of the Day on August 25, 2026
West Midlands slang word for rockers, bikers, greasers etc. In the late 1980s it was used by the UK music press to refer to a specific scene centered around the bands Pop Will Eat Itself and Crazyhead. The term never found favour with readers of 'the inkies' (Sounds, Melody Maker and the still extant NME) and was soon dropped. Now often used in predominantly working-class areas of the midlands and the north to mean someone who listens to rock-derived music and/or dresses in a manner that suggests they affiliate themselves with rock music of some kind.
