And I am still mildly bullshit

And I am puzzled about the meaning of bullshit as used in this context. Does this mean peeved? The only slang meaning of bullshit I know, as confirmed by my slang dictionary, is nonsense.

Interesting - whilst looking up bullshit, I discovered a synonym for bullshitter and bullshit artist which I'd not yet heard: bullshartest, which is, apparently, Australian.
