The act of partaking in vigorous sexual acts or coitus between that self-promoting psuedo-billionaire Donald Trump and two other persons (usually someone like one of the Bush twin daughters and myself).
Can also involve his wife Ivana, his bird looking daughter Ivanka etc etc etc.
Note: Due to therapy to combat his balding head, The Donald is impotent and would most likely be the one penetrated or do the penetrating with a 12 inch black latex strap-on.
Kwame: "What did you get up to this weekend?"
Douglas Hardy: "I fucked Donald Trump while his stork-looking daughter Ivanka fucked me with a strap-on."
Kwame: "That be called a menage-a-Trump. Been there - done that. The Donald and myself both nailed Omarosa during the 1st season of The Apprentice."
Douglas Hardy: "menage-a-Trump city!!!"
