When looking for the grundle, keep your eyes peeled for:
1. Looney Tunes and/or Alf shirts
2. Heavy, tried breathing and weezing
3. French fries in a cup
4. Dirty children (Often found orbiting the grundle)
5. Hazard level B.O.
2. (Obscure) Unkempt, often awkward character who just doesn't seem to fit with the rest of the group. Unrelated to 1; originated in Cape Breton, Canada, but has spread as far as Australia.
2. I feel like the family grundle.
