Yes, it is about Toby Vail (ex-girlfriend of Curt), no, it's not about heroin or meth and yes he did write it before he dated her. he was so nervous around her he got sick and would throw up. also on a lyric, to "shoot the s--t" is a slang phrase to converse with someone and to just bulls--t, not to shoot heroin or as another term for meth. also on a side note it is through toby vail that he met kathleen hannah who spray painted on a wall "kurt smells like teen spirit", meaning the deodorant, although kurt had never heard of that brand he thought she meant teenage spirit.
Чети си, чети. А "beat me out of me" moже да се отнася за абсолютно всичко. A това той самия го е обяснявал не веднъж по интервюта.
