I guess there are different types of nose pickers. I know this because I sit at stop lights, which seems to be the preferred time to do nose picking. Not me, of course. Everybody around me. Okay, not everybody, but maybe 17% of the drivers sitting in cars around me.
I’m thinking this says straight because the finger is going straight into the nostril, rather than coming in at an angle, which is definitely a tactic some NPs use.
Either that or it’s commentary on heterosexuals that I don’t quite get. Maybe it has something to do with boogers.
