Word formation: diminutive
'Kerlchen' (little guy) is the diminutive form of 'der Kerl' (guy/fellow). The ending '-chen' makes the word neuter ('das Kerlchen') and expresses that someone is small or perceived as small.
EXAMPLE

Look, the little guy can already walk!
Register: colloquial
This word clearly belongs to colloquial speech. It is rarely used in formal or written contexts, because it can sound either very familiar or slightly condescending.
EXAMPLE
„Na, du kleines Kerlchen, wie war dein Tag?“, fragte der Opa.
'Well, you little guy, how was your day?' Grandpa asked.
Context clue
The meaning depends strongly on the context and the adjectives used. In combination with 'klein' (small/little), 'frech' (cheeky), or 'süß' (cute), it usually refers to a small boy. With adjectives such as 'arm' (poor) or 'unglücklich' (unhappy), it expresses pity for a man.
