Sex, when administered by a female with the intent of making her partner feel good about himself. Women often engage in this behavior with friends who are unable to obtain pussy on their own and with whom they would never sleep with under normal circumstances.
Taylor wouldn't stop bitching about his ex-girlfriend's new guy so I tossed him a pussebo. He's got a skinny pencil dick, no wonder she broke up with him.

Do you remember my really fat friend, Chris? His cat died last week and I gave him a pussebo. He almost crushed me to death, but at least he stopped crying.

Get the Pussebo mug.
When you didn't get to the pussy but, you're so stoked that you feel like you did.
"I almost got it in! It felt great! "
"Yo, you're suffering from that Pussebo Effect! "
