Example:
Examples of stereotypes (regardless of accuracy):

"All cheerleaders are skinny, skanky, and anorexic"

"Why don't all you stupid emos just bleed to death, you depressed attention-seeking whores?" (someone actually said that to me)

"OMFG, like, Miley Cyrus!!!"

Example:
D1:Dude, why are all emo kids always dressed in black and calim to hate life?(Sarcastic)

D2:I know right?(non-Sarcastic)

D1:What a stereotype.

D2: Oh you were being sarcastic? I was being serious, because all emo kids DO hate life and dress in black...

Example:
"Of course Hakeem won the high jump, he's black."

"That is such a stereotype!"

"That it is, but it's true."

"Ignorant prick!"

Example:
I hate stereotypes about my people.

Example:
Drew Peacock- " Hey Otto, I knew you were black but I didn't know that your dad was born in Africa! That's cool."
Otto Wanaduyu- " Yeah, he is."
Kenny Naylor- " Wait a minute, does that mean that he has a click in his name? ... Oh I'm so jealous of him!"
Harry Buzzerd- " Not all Africans have clicks in their names."
Otto- " Actually, his first name is Dapopo. I guess the whole click thing must be a stereotype."

Example:
Guy 1: I met this hot chik from Hawaii
Guy 2: All women from Hawaii are sluts, I met one yesterday
Guy 3: You're just stereotyping. How can you judge an entire group of people based on one person?

Example:
1.) That all white women have flat booties.
2.) That all Jews are greedy.
3.) That all blacks are lazy, on welfare, and don't believe in marriage before child barring.
4.) That all Asians are good at math.
5.) That all Arabs are angry people that like to blow shit up.
6.) That ALL black men are hung like elephants.
7.) ALL white men are hung like squirrels.
8.) All blacks crave chicken and watermelon.
9.) All blacks are hostile and will quickly bust a cap in your ass.
10.) That all Mexicans like to drive around 15-17 deep in a small ass car.
11.) That all white people get angry when they cant get jobs and see others moving ahead.
12.) That all Asains like to eat rice and drive slow.
13. That all Irish people are drunks and eat potatoes.

These are just a few..however not everyone live this lifestyle and therefor should be judged on individuality instead of being grouped as a whole.

Example:
Stereotype for Goths are black clothes, black makeup, depressed, hated by society.
Stereotype for Punks are mohawks, spikes, chains, menace to society, always getting in trouble.

Example:
That's a vicious stereotype about (insert favored minority group), and the fact that people believe it is most of the reason why (insert negative outcome caused by stereotype).
