Jefflon 

Someone who has a purported level of subject matter expertise, yet consistently shies away from any circumstance when that expertise may be called into question for fear that the knowledge castle of sand will be revealed.

Boy Wonder just had another Jefflon moment. He was asked to speak about the recent OCIE release and just weaseled his way off the agenda again.

jeffson 

Jeffson is the most perfect person in the world. He is someone you can love within the first few seconds of talking to him and want to have in your life before even fully knowing him. He put others before himself and always makes sure those he loves are safe and okay. He is the pure definition of perfection and nothing less than that. He is definitely someone who is the combination of cute and sexy all at the same time and will always leave you with a smile on your face and dying laughing. He is someone everyone needs. Just not mine <3

“Jeffson is so fine ”
“He’s so perfect, his girlfriends so lucky”
