To be back on one's bullshit is to regress to a former state of being, often a rather unhealthy and self-destructive state. It implies falling back into one's old ways and habits after a
brief period of "self-reinvention".
Being back on one's bullshit is not necessarily a bad thing per se. Perhaps that
person had come to terms with their quirks, absurdities, and insatiable/irrational desires. No longer do they
try to repress those self-destructing behaviours and compulsions in hopes of becoming
better, because they know that one
day they will eventually give in; they can run but they can't hide from their true sordid selves. In other words, they continue to seek self-improvement and strive towards self-mastery, but they
don't
try to repress their former bullshit. Besides, that bullshit defines you and who you are and you can't feel like "you" without it.
Jennie: Jimmy wth?? What's up with those cross-dressing pics you sent me last
night, I thought you had already
broken out of that paraphilia of yours
Jimmy: Well what can I say, I'm back on my bullshit, and I
don't intend on hiding it anymore.
