Completing a task with such grace and fluidity that the onlooker will lose appreciation for how difficult a task it really was.

Noun: a friend who is usually only called upon by a friend when a more primary/prominent friend is unavailable.

Taken from the term “second string” in an athletic competition situation. In football, if the star quarterback gets injured during a play, the second string is called off the bench to replace him/her. A “Second String Friend” is essentially benched until needed, if ever.

Synonyms: Plan B, Second Choice, Secondary Friend, Benched Until Needed

The state of extreme smoothness. Smooth behavior in an individual is usually demonstrated by:
- fluidic movements that may lead you to believe this person has no bones or nervous system
- the complete lack of bodily hair that allows them to avoid wind resistance and retain their cool
- the strict avoidance of any sudden outburst in emotion or reaction to situations that would normally elicit unsmooth behavior
- a self-acknowledgement that they are smoother than every one around them

Note: achieving such a level of smoothness is normally obtained through a process called “smoothing up”.

a) Used when someone does something of skill and makes it look easy.

b) Used in a sarcastic form for when someone has messed something up.

To be extremely cool. Setting your own trends doing what you like!
Or if something is smooth it means in your own smoothness you think it is smooth.

Smooth is not rough or hard, but a soft and easy kind of grace. A smooth person thinks they're better than you, but is so smooth you'd never know.
