It is self explanatory slang, referencing the exchange of one word (squirrel) with another (girl) in the name of a popular scout club that, in real life, sell cookies. It is merely a play on words and how they can sound so funny together.

When you bump your head and eat a cookie you can get a severe head ache. It can also rot your brain and make you stupid.

A smash hit made by the South Korean girl group Red Velvet. Could be interpreted as a song about relaxing and forgetting about the stresses of life by enjoying a sweet treat ie a cookie. #Cookie Jar is used in the same way as #TBT in reference to just enjoying life NOT FISTING
