It is a soft 'G,' pronounced 'jif.'

Imma still call it a GIF tho. 
Chris Gerringer is the creative behind Paperbeatscissors! and he has designed my favorite gif of all time. The state of the world is a garbage fire right now, but there was this moment, this perfect moment where we were all distracted by these 2 adorable children crashing their fathers television interview. Chris captured the joy and much needed distraction in gif form. Thank you Chris!
