Phantom Friend 

More of an acquaintance. Most happen to be egocentric people.
They either

1) Share goodtimes with you, but when things get tough, they suddenly disappear.

Or

2) Are like a gold digger, but for the joy of having a friend instead of money. They are only a friend to benefit themselves. Once they've had their fill, they disappear until they repeat the process with another and feel lonely again.

Turns out they were just a phantom friend. After the fun ended, she just disappeared.

Best Friend Potion 

What 2 best friends drink to get rowdy and have slumber parties. Often followed by taking turns vomming in the toilet the following morning.

Corner Friend

Similar to a tag along but you keep them around because they are occasionally funny. Often found dwelling in the corner of social circles.

Sam: Man I'm really bored...
Tom: *says some random shit*
Sam: Haha, this is why we keep you around tom, you're a real corner friend...

A true friend is someone that loves you and would never go behind your back!! You can always trust them even with your biggest secrets.
