B.O.B (Big One Brewing) - This generally occurs after eating a big greasy meal. Your stomach starts to churn and you know that you should be looking for a toilet fairly quickly. B.O.B is often followed by prarie dogging
which is then followed by crowning. It is possible to go from a B.O.B to a massive exposion bypassing prarie dogging and crowning
I just ate a burrito, and I feel a B.O.B. Please show me the bathroom before I leave it on the floor.
