Hijinks are pranks, shenanigans, tomfoolery, getting into and out of trouble. Those things are associated with the bard.
The tweet also mentions laughter in the scrum, which is probably a reference to Tasha’s Hideous Laughter, and teasing and taunting, which probably points to Vicious Mockery. Those are two iconic spell/cantrip that the bard can cast.
I just remembered this today ...
And i wonder ...
The final part of that tweet "there will be no teases, taunts, or tells this time" ... sound to me pretty monk-like ... dont it?
Man can dream.
