A Belgium
A Belgium is when your partner thinks they're getting a slow and easy ride, but you bust out a full-on ramming session like a tank crashing through a buffet.
'I thought we were doing it gentle!' he screamed as I launched into him like a bullet.
'He just went full Belgium on me after I called him a bad dancer.'
'I told her I was going to take it slow, and then she Belgium'd me.'
