खुद को बचाने के लिए किसी को धोखा देना या बलिदान करना (khud ko bachane ke liye kisi ko dhokha dena ya balidan karna)
"He threw his colleague under the bus to avoid getting fired."
"नौकरी से निकाले जाने से बचने के लिए उसने अपने सहकर्मी को फंसा दिया।" (naukri se nikale jane se bachne ke liye usne apne sahakarmi ko fansa diya)
sometimes it's okay to ignore rules
manipulating people into divulging confidential information...
to stay focused on your goal
to show support or appreciation by liking or sharing someone...
to get an enthusiastic applause from the audience
to start implementing a plan or idea
