A warning given when someone tries to talk around someone on a certain subject, but the person is very familiar with the subject matter.

Employer: It seems you tested positive for marijuana.

Employee: I was at a party and people were smoking around me.

EXAMPLE 1:- "My dad paddled to the Antarctic in his dingy last week and killed a killer whale with his pen knife"

EXAMPLE 2:- "I pulled a wheely last night on my bike and the front wheel fell off, i ended up riding round on one wheel for two hours and at one point i was going so fast the police tried to pull me over for speeding but i couldn't stop because i only had one wheel. I only stopped when i rode into the lake where i found my front wheel at the bottom!"

EXAMPLE 3:- "what have you had for your tea Bobby?" "My mam's just made me a lovely steak dinner with onion rings chips and creamy pepper sauce" - When it's quite evident he's had beans on toast due to there being beans all down his front !

Bata Bullshitter 

A Trent University student who spends most of their time outside the Bata steps talking about things that they pretend to feel, dreams they won't chase, and hoping that staying in school will never allow them to confront their failure to chase their dreams head on.

T: I really want to have my own place, go to grad school, and really live for myself. It's all other peoples' fault that I can't accomplish these things.

N: Trust me, grad school's great. It's alot of fun...wonderful. I dream of being a prof, or just having sway over other peoples' fertile young imaginations because someone torched mine so long ago that it'll render me thoughtless to how I treat others permanently. Academics is the place for me.

Geez, there's alot of Bata Bullshitters out today
