The literal meaning of Jhooth is lie/untrue. But when somebody says "paani/khaana jhootha kar diya" it means it's been used/eaten/drunk by somebody else/it's not fresh anymore or not fit for consumption. It's used only for things which are edible. So if somebody has used your pillow I can't say Pillow jhootha ho gaya. Hope I've made it clear.

it is nice line i call my sister for a glass of water she drink a little from a full glass of water so this is not a fresh water so it is sad that "baby ap nay mera pani jotha ker dia"

"baby ap nay mera pani jotha ker dia" can be translated as: "Baby, you have sullied my water."
