The infamous other meaning of "toot" is very specific to US English. Like calling a tap a "faucet". As used in England, and thus in Aotearoa, a toot is the blowing of a horn (eg tooting at someone when they cut you off in traffic). This always seemed very appropriate for posting on social media, regardless of the elephantine associations ;)
