I think that I'm feeling the vibe
I see the love in her eyes, I see the feeling
Kendrick is mocking the “feeling” of alcohol. Stating he’s one shot away from death, but somehow still having fun (“feeling the vibe”). He’s making note of the false feelings alcohol gives everyone when consumed in to large of quantities. He says he “thinks” he’s feeling the vibe alcohol is suppose to give you, from whats he’s heard from other people.
Also, it’s common that when most people are drunk they are more attracted or in love with people, have lower inhibitions and are more wanting & willing to have sex.
