Apparently so. Let's do the math -
D I C K B O C K = O N S M A C K
Assign each letter a numerical value of its position in the alphabet, and we get:
4 9 3 11 2 15 3 11 = 15 14 19 13 1 3 11
Now, let's add:
4+9+3+11+2+15+3+11 = 15+14+19+13+1+3+11
58 = 76
Add again:
5+8 = 7+6
13 = 13
And to remove all doubt:
1+3 = 1+3
4 = 4
Therefore, Dick Bock was indeed on smack.
