Can be used in a sarcastic tone, meaning heavy furry undertones that are unwanted and/or overwhelming.

If not used sarcastically, the word can just simply mean something was fantastic but was furry related.
Sarcastic:
This store is furrtastic, and it's freaking me out, let's leave.

Non-sarcastic:
Last weekend's con was furrtastic! I met all of my furriends from the forum and we had a blast!
