Trucker's (trucker's) tan is far more commonly used than "trucker's arm". It's used when recognizing that a person's left arm (driver's side arm) is tanner/redder than his right arm.
It's used in the same way a person would be said to have a "farmer's tan" if both his forearms were tan/red up to the point where his (short) shirt-sleeves end on the upper part of the arms.
With the ubiquity of air conditioning in cars today, "trucker's tans" are seen much less frequently. But if noticing a person's left arm is red/tan (but not the right), say, "Hey Joe, you been driving a truck? You got a 'trucker's tan', my friend!"
In the same way, upon noticing the whiteness of a friend's upper arms in contrast to their forearms, you might say, "Hey Joe! You been out farming today? You got a 'farmer's tan', my friend!"
Spending the afternoon professionally tanning in your back yard, at the beach, at a local pool, etc. in place of employment. Pro-tanning can be done in a bikini, tankini, or one piece with friends, family or even alone!
This inexpensive activity requires few, if any supplies. Some suggestions to take your experience to the next level are sunglasses, tanning oil or sunscreen, lipgloss with SPF, and music.
For optimal results, Pro-tanning should be done between the hours of 10:30 am and 3:30 pm.
Note: You can also use the term "Pro" to other tan related topics such as "Pro-burning" (inexperienced Pro-tanners) or "Pro-failing" or "Pro-success" (which is Pro-cess for short)
