About GRR
GRR is the sound of a growl, an expression of anger or annoyance. GRR has no vowels, so it helps an all-consonant rack with a G and two R tiles. Picture a cartoon dog with its teeth showing. Like the other no-vowel noises (BRR, HMM, PST, SHH, TSK), it often surprises the table, so be ready to explain it. In comics it is the sound of a growling dog, and at the table it is the sound of someone who just drew a seventh consonant.

GRR scores 4 points
Before any bonus squares: G 2 + R 1 + R 1 = 4. On a double-word square that's 8, on a triple-word 12, and every letter bonus under one of these tiles is applied first.
Example: GRR as the first play
Later in the game, put the G on a 3L square and GRR is worth 8 before any word bonus.
