The band name is an abbreviation of “The Obliteration of Humanity”.

!T.O.O.H.! disbanded shortly after putting the finishing touches on the album Order and Punishment due to financial issues (caused by Elitist Records being abandoned by Earache Records, who took the album out of print only two months after its release). However, in September 2011, the band reunited as a two-member project consisting of Humanoid and Schizoid.
