I've been that drunk. I can sympathize with the head bobbing and loss of balance.

The only time I hit my head that hard (I think) was when we stole the tank of Nitrous from the Chem Dept.  One halacious whippit, and i was out cold.  I remember head hittin the floor and feelin like a basketball.

EDIT:  The poster does not condone or support the use of illicit materials, including alcohol and tobacco, by minors.  This is merely the ramblings of a deranged mind.
