We're not entirely sure what's going on here...
But according to Facebook page 'Spotted: On Irish Rail' this character was spotted on the 6.40am train from Newbridge to Heuston Station today.
The post reads:
To the lad on the 6:40am train from Newbridge to Heuston with your jacket over your head chanting "woooo I'm a sesh monster" whilst rocking back and forward. Any chance of an invite next weekend ?
Are you the sesh monster? If so, what on earth is going on here?!
