Tunasub

Tunasub was created by some filthy minds on the twitterverse as an allusion to masturbation. Backwards it spells bus a nut. Used as an incognito way to announce that one has or has the intentions of masturbating.

After a long day, I like to come home, shower and tunasub.

Tunasubbing

When you're having sex and your partner yells "tunasub" before ejaculating and begins tickling you uncontrollably.

Yo man, me and my girl were having sex and right before I busted my nut she yelled "TUNASUB" then started ticking me. I swear man, she loves tunasubbing me more than she loves food.
