atmospheric reentry 

A sudden change in mood from euphoric and positive to depressed and negative due to a certain event or information.

I was really happy, but then my bad mark caused an atmospheric reentry.

Work Reentry 

The first few hours and in severe cases the entire day after returning to work from vacation. Symptons include acute depression, anxiety, and in severe cases panic attacks and an uncontrollable urge to run.

My hunny and I just got back from Aruba and I have work reentry so bad I am ready to puke.

rear entry 

1. To have sex from behind (can be either vaginal or anal)

2. Ideal for stimulating the g-spot or prostate.

Dude 1: Jill and I usually do it missionary, but yesterday we decided to mix it up and did it doggy.
Dude 2: Hell yeah, it's all about the rear entry.

Rear Entry Position 1 

1. Also known by some as "doggy style" the rear entry position is fairly easy to assume. The woman gets either on her hands and knees or lays stomach first on the bed with her lover behind her. He is on his knees or sometimes his feet, and develops leverage by grasping on to her hips. Depending on preference the man's legs can be inside of the women's legs or outside of them. Couples may wish to have the woman's legs closer together because it creates more friction between the penis and vagina.

I like the doggy style!

smooth reentry 

1) A man who, after spending an extended period of time in a long term relationship, effectively participates in the modern dating scene without undo difficulties.

2) A space vessel entering the atmosphere with only a moderate amount of turbulence.

Bubba: Dude! Check out the arm candy on Bob! How'd he manage that? That guy hasn't dated since Bruce Willis had hair!

Jack: I see bro. That's a smooth reentry right there.
