This is the ship name for the iconic on-screen pairing of Aman Tripathi (Jitendra Kumar) and Kartik Singh (Ayushmann Khurrana) from the 2020 Hitesh Kewalya directed movie Shubh Mangal Zyada Saavdhan.
The supporters of the cutest ever ship have a small but strong internet base across platforms like Tumblr, Instagram and Archive of Our Own (AO3), where they regularly post and hype about various heart wrenching Karman edits, hilarious Karman memes and Karman fanfics across different genres.
The Fandom members are also very emotionally charged and needy about the possibly non-existent or possibly hidden deleted scenes from the same movie.

A pairing between a man who is as short as his temper (Aman Tripathi played by Jitendra Kumar) and a pride-flag-wearing-superhero (Kartik Singh played by Ayushmann Khurrana) from Bollywood's first mainstream gay rom com Shubh Mangal Zyada Saavdhan (SMZS). Fans of this pairing are will cry if you mention Raakh (a song from the movie) at any given moment and generally agree that Hitesh sir (the director of SMZS) is a genius.

Just don't mention deleted scenes (namely the 'aap hi duniya ho scene' and the missing Ganga kiss).

Fans of this pairing also has an unholy affinity for mahogany tables, velvet curtains and belly chains.
