Bi

"Thou shall bisect the cake!" 

Said my brother. He was bipolar and bisexual, always riding his favourite bicycle, despite bipedal, born in a bicultural family, raised to be a bilingual.

"Ever used bivalves as a metaphor for 'the one'?"

But he was mainly bipolar. He believed in bipartisanism, consuming drinks made of bifunctional molecules biweekly. He said his job was to put together biannual reports bimonthly. What does it even mean?

"Who would ever celebrate bicentennials?"

But he was in a bidirectional relationship, with me. What? there were bilaterals.
