Waking a Polack up in the morning by spraying your load in their face. Derived from the Polish tradition of Smingus Dingus where Poles throw water in each other's faces to wake each other up on Polish New Year and shout "Smingus Dingus".
Alina drank so much vodka last night she passed out. I tried to wake her up nicely in the morning for a rogering but she was out cold so I just had to Schlongus Dongus in her face. That woke her up.
A king of simps. Simp is someone who put people that they like in a pedestal treating them like they are royalty.
Schlongsimp is someone like Juan. Juan was playing with his friends. Maria asked if Juan wanted to play, so Juan said that he was too tired, betraying his friends, and went to play lol with his simp queen!
