A smalllaptop you place on your “tummy” while laying down so you can watch porn and browse with one hand while the other reaches around the screen and takes care of business.
Why you got them spats on your laptop? Yo, this my tummytop...use the other computer.
a tummyton is a little brother that is amazing and loves being called by this name. If you are a tummyton you most likely play a lot of fortnite and have a ps5. But are very ruthless.
me: Holayoung tummyton, what are you playing
tummyton: get the fuck out.
