look up any word, like thot:
 
1.
One thrust shuff: that awkward sexual encounter (frequently going hand in hand with losin it) when a penis enters the vaginal area for about .10 seconds (hence the "one thrust") and then proceeds to exit and terminate the sex act. Not to be confused with a beej smeej.
"Wow I just had sex for the first time. Is it supposed to be such a short little dance?"

"Ooooh sounds like you just had a one thrust shuff!"
