Professional Cock Block 

A secret way of blocking anyone from dating a certain individual.
Professional Cock Block artists have their own secret way of doing things.

They usually do it to be protective of someone they care about.

Person 1: He is such a Professional Cock Block.

Person 2: Well maybe it wasn't meant to be.

Person 1: Be cautious around those Professional Cock Blocks, they know how to trick you.

Professional Friend Hopper

Someone who doesn't want any of the commitments of friendship but wants to reap all the rewards that come with having that or those friends. They're never there when you need them but never have a problem asking you for things or help. They're in the "friendship" for all the wrong reasons.

"Have you ever noticed how none of their friends remain friends for very long? Like they may know a lot of people and talk to a lot of people but they never hang out anymore?"
Only professional friend hoppers jump from group to group or person to person like that.
