I think "wet bulb" describes how the temperature is measured, not a specific temperature or humidity.
NATOpedia:
At 100% relative humidity, the wet-bulb temperature is equal to the air temperature (dry-bulb temperature); at lower humidity the wet-bulb temperature is lower than dry-bulb temperature because of evaporative cooling.
Libs are perfectly understanding that people "don't take too kindly to the heads of state", but the only acceptable tactics in response are drawing shitty art depicting them with small penises, maybe coming up with a probably-racist nickname if it's really serious.
