There were enough responding tweets pointing out the folly of comparing himself to the 1700-odd severely endangered animals that make up India's current population of actual tigers.
Several of these tweets were sarcastic or plain dismissive.
#InternationalTigerDay cause if it were NationalTigerDay people might mistake it as Tiger Shroff's birthday.? Alokita (@dumbevil) July 29, 2016
In Tiger's defence, he wasn't the only one making capital of the name - PETA India recruited the 26-year-old actor to write to Minister of State for Environment Anil Dave petitioning to focus on protecting the tiger's natural habitat (not Bollywood).
A separate thread of tweets trolled the actor for an interview with Mumbai Mirror in which he reveals that he was nicknamed 'Tiger' because he used to bite and scratch as a child. His real name is Jai Hemant Shroff.
AIB member Rohan Joshi flagged the interview - which was run with a photo of the Flying Jatt star posing before a caged tiger and a headline that specified the timing was not inadvertent. Twitter did the rest.
@mojorojo What a coincidence. I was named Tiger too for the same reason. They changed it to Rahul once I stopped biting? Rahul Subramanian (@RahulNotAGandhi) July 29, 2016
@mojorojo bite = tiger Bite = dog? Coat and Gown Ninja (@mridul_chakra) July 29, 2016
@mojorojo He does fantastic on-screen kicks now. Should consider calling himself Donkey Shroff now.? Rajesh K Sharma (@rajeshksharma) July 29, 2016
Meantime, actor Rishi Kapoor randomly tweeted about Tiger Shroff some hours previous.
Blessings to another son of mine-Tiger Shroff. What blessed dancer and looker after the Greek Hritik! My bestest! pic.twitter.com/jcTABaRhdG? Rishi Kapoor (@chintskap) July 28, 2016
He was effusively thanked by both the actor and his mother Ayesha.
Last seen in April's Baaghi, Tiger Shroff has A Flying Jatt with Jacqueline Fernandez coming up.
