It was a promposal for the (Middle) ages.

An Ohio teenager went viral after asking his girlfriend to prom by pretending to be a prince riding around with his knights.

Gavin Gillig took things really old school Tuesday when he asked Gianna Masterlasco, 17, to attend the event with him by enlisting the help of his friends, Newsflare reported.

In the video — which was captured by Masterlasco’s father, Patrick — the confused teen can be seen opening up the door of her house to reveal one of Gillig’s friends, RJ Coldren, blowing a horn to signal his compatriots.

Laughing, Masterlasco turns to her father as a soft clopping sound is heard approaching the house.

Gillig, dressed in a red cape and crown while riding a pole with a horse head, appears flanked by two friends dressed as knights.

One of the teens then unfurls a large roll of paper.

“Hear ye, Hear ye,” said one of Gillig’s friends in a mock British accent. “Sir Gavin Gillig, son of Sir Trevor Gillig, first of his name, destroyer of porcelain, tamer of the beast Chewbacca, slayer of the bucks and scourge of all those things that smell nice and clean.

“Cordially invites you, Miss Gianna Masterlasco, to the royal gala filled with fun fellowship and fellow acquaintances on 6 May 2023, the year of our lord,” continued the friend before asking the laughing girl her response.

“Yes,” replied Masterlasco as the man flips over the paper with the question “Prom?” and gives her a paper crown.

“Ah, Wonderful. I will see you soon ma’am,” replied Gillig, still in character, before asking for his “horse.”

They then ride off as Masterlasco’s father is overcome with laughter.

According to the elder Masterlasco, the jokesters only rehearsed the proposal once.

“Got a text to open the front door and was not expecting this,” the dad told the outlet. “They had one rehearsal and decided to just go for it.”

The Post reached out Gillig for comment.

A copy of the video was later posted to Instagram and users went wild over the hilarious proposal.

“One of the greatest things I’ve ever watched,” said one user.

“This made my day! Does this kid know Monty Python,” asked one user referencing the way the horse noises were made.

“The level of dedication from the friends. I’m here for this,” laughed a third person.
