functino

   [uncommon,  U.K.;  originally a serendipitous typo in 1994] A pointer
   to  a function in C and C++. By association with sub-atomic particles
   such  as  the  neutrino,  it  accurately  conveys  an  impression  of
   smallness  (one  pointer  is  four  bytes  on most systems) and speed
   (hackers  can  and  do  use arrays of functinos to replace a switch()
   statement).
