Afterbye 

When you say your goodbyes on a telephone call, then you suddenly remember you had something else to say and re-ignite the conversation.

1) "ok mate, take care, speak to you soon, bye....oh wait! Did I tell you about...."

2) Dude 1: "Man, I'm so tired today, I was on the phone to Michelle last night"
Dude 2: "Till what time?"
Dude 1: "Well we said goodnight at about 11pm, but we Afterbye'd till gone midnight!"

Afterberner

Following the initial berner (pre boner) and after experiencing climax with a boner, the afterberner is what's left of your penis after sex.
Usually awkward and unwanted the afterberner will leave it's owners with a slightly larger, limp and soft berner.

"Hey Danny tuck that afterberner in man you want your mom to see that?"
"Maybe"

afterbreath 

The smell, distinct from the taste, of someone’s breath after eating out their girl.

Man, she tasted amazing last night, but my afterbreath smelled like a rotten fart.

Afterbreakup Bitch

A person who talks shit after you were in a relationship and tries to fuck up your life even if they are the ones who ended the relationship.
