The super virus /sexually transmitted disease that has resulted from New England Patriots Tight End Rob Gronkowski having sex with everyone's girlfriends, wives and favorite porn stars. The condition can only be cured by a heavy dose of antibiotics or if Rob Gronkowski opens his mouth and speaks.
If the Patriots game just ended and your wife seemed to only be cheering for Gronkowski and now she's horny... be careful she may have the Gronk.
If after sex you feel nauseous and dirty and things just don't seem right, you may have to go to the doctor... you might have the Gronk.
(Note: There is a higher chance your lady has the Gronk if you are a Jets fan)
