if you look, each of the letters in the f-bomb are one character away from each of the letters in divi.. d-f, i-u, v-c, i-k.... Anyway go to Settings > Language and Keyboard > Touch Input > User Dictionary to delete it (or add or edit any while you're at it).

On a side note, I think when I get mad I'm going to tell people to go divi themselves.
