cangrejear

Literally to fish for crabs, cangrejear also has a lively figurative range: to retreat or back down (like a crab scuttling backward), or to backpedal on a stated opinion out of fear or excessive deference. Regionally, in Barinas (Venezuela), it can mean to go for an aimless drive with family or friends — and in some vulgar registers it's crude slang for touching someone sexually.

• Pasamos la tarde cangrejeando en la playa. — We spent the afternoon crab fishing on the beach.
• Prometió algo y luego se puso a cangrejear. — He promised something and then started backpedaling.
• Los domingos, cangrejeamos por los pueblos cercanos. — On Sundays, we go for aimless drives through the nearby towns.

Context decides the meaning here — literal crab-fishing, backing down from a position, a leisurely drive (Venezuela), or vulgar slang — so don't assume one fixed translation applies everywhere, and avoid the word in careful or formal speech since one of its senses is crude.
