"Du siehst geil aus."-> "You look sexy."
"Das Auto ist geil."->"The car ist cool/hot."
Do not(!) use this word in a conversation, if these people your talk to are no close friends or relatives. Could be misunderstood.
The best colloquial word ever established by the German language. It has slowly assimilated itself into English speaking culture, particularly the Southeast of America. These cities such as: Charleston, Charlotte, Atlanta, and Chattanooga the word 'GEIL' is used frequently and interchangeably between the people whom reside there.
Simple in Context:
Im so Geil! (Fucked up)
Wanna get Geil? (Wanna get wasted/fucked up/nutty/lit..etc)
She's fucking Geil! (She is hot and DTF)
Hey Chad, you down to get GEIL tonight?
Hey is that Wendy Brown over there by the bartop? Yea, it is chad. Damn, she's GEIL.
Which is a problem for the Irish, common mistakes when speaking German are: Guten Tag, ich bin Ira und ich sprache Geilisch, denn ich komme aus Iraland. (Correct words are Ire not Ira, Gielisch not Geilisch and Irland not Iraland)
Translation of that is: Good day, i am crazy and i speak sexy talk, because i come from Crazy land
Guten Tag Paddy, wie ist dein Kopf... Ira mann??... warum sprachst du Geilisch nicht?... Ich habe gedacht, du bist Ira!
