Someone who tries too hard to impress someone. Most likely a student to a teacher or an employee to a boss. They try to make themselves noticed, and the person on the receiving end usually tries to respond in a polite way. Everyone else think’s that the kiss ass is a little bitch and an attention whore. Most of the time they are socially inept. They think they are better than everyone.
Kate: “Um, Ms. Teacher, I finished all of my work a month early! What do I do now?”
Teacher, trying to be nice: “Oh wow Kate, how impressive? Uhh... why don’t you go over there and read?”
Kate: “Of course my favorite teacher in the whole-wide-world!”
Everyone else: “what a kiss ass

Someone eager to please another person out of desperation by paying compliments and other pathetic stuff.

Ass kisser "You're Irish, oh cool Irish people are so badass are so sexy"

Normal guy "Yeah and you're a feckin kiss ass gay, You weren't saying that when my family came to America ages ago were you.

Ass kisser "I'm Irish too"

Normal guy "That's it kissing my ass is one thing but claiming to be Irish when you're not is just asking for a boot up your ass"

A true kiss ass is not somebody who's been nice to somebody else. A true kiss ads is somebody who's friendly with authority figures so that the authority figures will take care of them when times get rough.
True kiss ass- Officer, he threatened me. Go arrest him, he's being mean to me!
Police or other authority figure- I don't want to hear what the guy did any more. Take control yourself and quit running to me about everything.

Not a kiss ass-
Guy- Have a nice day.
Other guy- You're a kiss ass sir.
Guy- No, I've said something to you about your day, no more, no less. Fuck you and your day.
