Yeah, that one's not right. Unless he means he likes jerking off to massive loads? I went through a spell of being a literal wanker, back in the day. Everything checks out except for that phrase. If you're jerking off more than twice a day, your loads probably look like when you blow your nose right after you sneeze. And I don't mean when you sneeze a bunch of times in a row while you're looking for the tissue box, either.
