Anyone of those people could be him...
Or, he is inside the bus licking on his SBS6129A citaro
ambulance diecast model

!
And then he creates a nuisance inside the bus, shouting,
"SEETALOHZ R DA BEHZT!!!" Then SL kicked him out of the bus and
took away his SBS6129A.
SMB228X's Citarotitis struck and he went on to kick a KUB, thus
injuring the BC and his passengers. Police came and he was sent to
IMH by QX179R, no point sending him to Boys Home or else he lick
anything that is affiliated with Citaros, even scrap metal.
Make up story

.
Basically :
Any bus he licks = Scrap metal
Any person he licks = Gets AIDS and Citatotitis.
