For me it is the other way around. I have no idea about the American pop culture "characters" mentioned with out googling I have to have to assume they are made up names.
These are my guess for the meanings of the names/nonsense terms mentioned in panels 3-6.
- Tiger Woods: Protected forest game reserve with large cats, usually tigers. As opposed to Lion Veldts, protected grassland game reserve with large cats, usually lions.
- Snooki: Common name for a toy poodle.
- LeBron: Brand of baby shoe. Name derived from the concept of bronzing shoes, the "ze" was dropped and the "le" added for some sort of pseudo foreignness, see Häagen-Dazs.
- Lady Gaga: Childhood nickname of some aristocrat.
