The Ye toh mootne laga saala meme originates from the 2003 Indian film Gangaajal. In this Bollywood movie, Sadhu Yadav (the character played by Mohan Joshi) says this dialogue to Bachcha Yadav (the character played by Mukesh Tiwari) when local goon Nunwa starts peeing during captivity at Sadhu’s hideout. The English translation of Ye toh mootne laga saala is he has already started peeing. The popular use of the Ye toh mootne laga saala meme is to mock someone who feels vulnerable.
